A systems-first approach to building loyalty, scale, and momentum without chasing clients or content. Most people assume the Grateful Dead were successful because they were different. The reality is that their long-term success stemmed from how they structured everything, from distribution to engagement. No radio hits. No flashy marketing. No need to chase attention. They built a system that grew without constant promotion. One that kept people coming back and bringing others with them. If you’re a consultant, advisor, or technical expert, this model can work for you, too.

(aka: The Art of Talking With Your Functions Without Losing Your Mind) Functions are like little wizards in Python. You hand them some ingredients, they stir their magical cauldron, and-poof-you get a result. But here’s the catch: if you don’t know how to hand over those ingredients correctly, your wizard might either mess up the potion or throw a TypeError tantrum. So today, we’re going on a deep dive into function parameters: arguments vs parameters, positional vs keyword arguments, the mysteries of *args and **kwargs, unpacking secrets, and the sneaky pitfalls of default parameters. By the end, you’ll not only understand them, you’ll be able to explain them like an absolute genius. Let’s clear this up before we go too far: Parameters are the names you define in the function.

Introduction Incremental Static Regeneration (ISR) is a modern rendering strategy that combines the performance benefits of static site generation (SSG) with the flexibility of dynamic rendering. Unlike traditional static sites that require a full rebuild whenever content changes, ISR enables developers to update or regenerate individual static pages on-demand, after deployment, without rebuilding the entire site. This approach was pioneered by frameworks like Next.js, and it represents a middle ground between Static Site Generation (SSG), Server-Side Rendering (SSR), and Client-Side Rendering (CSR). ISR provides developers with the ability to serve pre-rendered static pages (for blazing-fast performance), while still ensuring that content can stay fresh and up to date. For example, consid…  ( 9 min )

The art of building is such an important curiosity to have. I fully embrace AI—I use it every day to write and ship software faster. It’s incredible, and I’d be lying if I said it hasn’t changed the way I work. But I can’t let go of my curiosity to understand the smallest moving parts. I can’t stop tinkering, breaking things down, and building my side projects brick by brick. That urge to build for the sake of building is something I’m deeply grateful for. Recently, I’ve been diving into microservices and APIs. Somewhere along the way, a simple question started haunting me: how is my code even reachable on my local machine? Sure, I know the surface-level stuff—HTTP calls, GET requests, JSON responses, the satisfying 200 OK. But what even is the HTTP server that makes this all possible…  ( 6 min )

In the ever-evolving world of statistical modeling, the question of identifying change-points in a dataset, points where there is a substantive change in a trend, remains essential.

AI Response Generator vs Chatbots: What’s the Difference? Digital interactions have exploded across industries. From customers expecting instant answers on social media to businesses struggling to handle thousands of support tickets, AI is filling the gap. Two terms dominate this landscape: AI response generators and chatbots. AI response generators create personalized, context-rich replies; chatbots automate structured, real-time conversations. Choose generators when personalization and nuance matter; choose chatbots for volume, FAQs, and transactions. The hybrid model—chatbot + generator—delivers speed, scale, and human-like empathy. But here’s the problem: many leaders confuse them, assuming they’re interchangeable. In reality, each serves a different purpose—one focuses on crafting …  ( 10 min )

If VS Code is my cockpit, AI extensions are the autopilot. I still fly the plane—but now I focus on the horizon, not the switches. In 2025, VS Code isn’t just an editor anymore. With AI-powered extensions, it has become a thinking partner that reviews, suggests, tests, and sometimes even explains my own code better than I do. Here are 10 extensions that actually changed how I work (and most devs I meet haven’t even tried half of them). 🔧 1. Sourcery – My Refactoring Sidekick ✨ Cleans messy functions, removes dead code, and suggests smarter refactors in real-time. 🤖 2. Sixth AI – All-in-One AI Engineer Chat, debug, and generate code—all inside VS Code. ⚡ 3. Vortex – AI Code Editor on Demand You highlight code → Vortex rewrites, explains, or tests it instantly. 🧪 4. Qodo Gen – Test Generation Beast Unit tests are boring. Qodo Gen makes them less painful by generating meaningful test cases. 🖥️ 5. VS Code Commander – Talk to Your Editor Ever tried chatting with your editor? 🤝 6. GitHub Copilot – The OG Co-Pilot Yes, everyone knows it. But here’s my honest take: ✍️ 7. Tabnine – The Privacy-Focused Alternative Copilot’s cousin that runs models locally for privacy-conscious teams. 🪄 8. Cursor – The AI-Powered Editor Not just an extension, but a VS Code fork built around AI. ⚙️ 9. Bito – Knowledge at Your Fingertips Explains codebases, APIs, and libraries in plain English. 🧩 10. Keploy – AI for Testing APIs Mocks + tests APIs automatically. 💡 How My Workflow Changed Before AI extensions: 30% time = coding 70% time = debugging, writing tests, cleaning code After AI extensions: 60% time = coding & designing features 30% = collaboration & review 10% = repetitive cleanup (which AI now handles) I didn’t just get faster.

Here's a story that might sound familiar: Sarah applies for a mortgage to buy her first home. She's got a steady job, decent savings, and what she thought was good credit. But the bank's AI system rejects her application in seconds. When she asks why, the loan officer – looking genuinely sympathetic – shrugs and says, “I'm sorry, but the algorithm flagged your application. I can't tell you why.” Sarah leaves frustrated and confused. Should she try another bank? Is there something wrong with her credit she doesn't know about? How can she fix a problem she can't identify? This isn't science fiction – it's happening right now, millions of times a day, as AI systems make decisions that affect our lives in ways we can't understand or challenge. We're living in the age of algorithmic decisions. …  ( 9 min )

In many Salesforce projects, developers often start by hardcoding configuration values (like API URLs, keys, or feature toggles) directly into Apex classes. While this might seem quick and simple at first, it creates long-term maintenance problems. Changing values requires code edits and deployments. Supporting multiple environments or services becomes tricky. Non-developers (like admins) cannot update these values. A much better approach is to use Custom Metadata Types (CMDT) to externalize configurations. This keeps your Apex clean, makes maintenance easier, and empowers admins to manage settings without touching code. Let’s take the example of integrating Salesforce with multiple cloud storage providers. Initially, you might write something like this. private final static String upl…  ( 7 min )

A few years ago, every app was racing to release a “Dark Mode.” It felt cool. It felt modern. And then… the hype wore off. Because here’s the truth: dark mode alone doesn’t solve the problem. Ever tried reading dark mode at noon, outside? → impossible. Ever switched to light mode at 2am? → instant headache. That’s where Adaptive Themes come in. 🎨 What’s Adaptive Theme Design? “I’ll just adjust based on your environment, your device, and the time of day.” Examples you’re already seeing: Slack & Twitter → auto-switching dark mode. Apple’s Liquid Glass (coming in iOS/macOS) → a theme that reacts to light around you. Web APIs like prefers-color-scheme → let your site adapt automatically. 👀 Why This Matters for UX Comfort first: no more mode-toggling every morning and night. Accessibility: adapts for people with light sensitivity or vision issues. Battery life: OLED screens actually save power in dark environments. It’s not about giving “light vs dark.” It’s about giving the right mode, at the right time, without asking. 🛠 How Devs Can Do It Today Use @media (prefers-color-scheme: dark) in CSS. Offer an override toggle (because choice still matters). Smooth transitions → no jarring white flashes. Test your app in multiple lighting conditions (not just your office desk at night 😅). 🚀 Final Thought We’re moving toward a future where apps adapt like chameleons. 💬 What about you? Do you stick with light/dark, or are you ready to embrace adaptive themes?  ( 6 min )

In 2023, when I was searching for a school to pursue my master’s degree, I wasn’t focused on the specific criteria.

When dealing with problems like autocomplete, spell checking, or prefix-based searches, a standard data structure like HashMap or TreeMap doesn’t cut it. This is where the Trie (pronounced “try”), also known as a prefix tree, shines. In this post, we’ll cover: What a Trie is and why it matters Core operations (insert, search, prefix search, delete) A clean Java implementation using arrays (children[26]) When to use Tries vs HashMaps A Trie is a tree-like data structure used to store strings efficiently. Each node represents a character. A path from root to a node forms a prefix. Nodes can mark the end of a word. 👉 Think of it as a dictionary where words share common prefixes. Example: inserting "cat", "car", and "cart" results in: root | c | a …  ( 7 min )

What is Big O Notation? Big O notation is a way to measure how fast an algorithm runs or how much memory it uses as the input size grows. It helps programmers compare different algorithms and choose the most efficient one. Why is Big O Notation Important? Helps optimize code for speed and memory. Essential for technical interviews. Used in real-world applications to handle large datasets efficiently. Common Big O Notations Explained 1. O(1) – Constant Time Description: The algorithm takes the same amount of time, no matter the input size. Example: Accessing the first element of an array. public void printFirstItem(int[] numbers) { System.out.println(numbers[0]); // Always O(1) } Best for: Operations where input size doesn’t affect perfor…  ( 6 min )

Every brand, regardless of size, depends on visibility in search engines to attract customers. The challenge lies in deciding whether to focus on Local SEO or International SEO. Both strategies help businesses connect with their target audience, but they serve very different goals. For a brand like scalethebrand, choosing the right approach can define how effectively it reaches customers in competitive markets. Local SEO focuses on improving visibility for searches within a specific region or city. It helps businesses appear in location-based results such as “restaurants near me” or “lawyers in Karachi.” This strategy is particularly useful for brands with a physical presence or services tied to a geographic area. Local SEO ensures that businesses dominate regional search results. Ranking …  ( 7 min )

From Advanced Remote Retrospective Psychology: When Basic Techniques Fail Your remote team keeps hitting the same problems because you're treating symptoms instead of root causes. The 5 Whys technique, adapted for distributed work, helps you dig deeper into remote-specific dysfunction. The Remote Work 5 Whys in Action: Problem: "The deployment failed" Why #1: "The tests didn't catch the bug" Root Cause Revealed: The real problem isn't the failed deployment - it's that your organization's measurement systems aren't designed for distributed work realities. Why This Works for Remote Teams: Standard root cause analysis often stops at "communication problems" or "process failures." The remote-adapted 5 Whys forces you to examine how distributed work constraints create systemic issues. Implementation in Retrospectives: When your team identifies a recurring problem, spend 10 minutes walking through the 5 Whys. Don't stop at comfortable answers like "we need better communication." Keep pushing until you hit organizational or systemic constraints. Warning: This technique surfaces uncomfortable truths about remote work that your team might not be ready to address. Use it selectively with problems that keep recurring despite multiple "fixes." → Learn advanced techniques: Advanced Remote Retrospective Psychology: When Basic Techniques Fail  ( 6 min )

The European Accessibility Act (EAA) came into force on 28th June this year. But what’s happened since June? On 7 July 2025, two visual-impairment advocacy groups (apiDV and Droit Pluriel), with legal support from the collective Intérêt à Agir, issued formal warnings to four large French retailers Auchan, Carrefour, E. Leclerc, and Picard Surgelés for failing to make their online supermarket services fully accessible. If the retailers haven’t fully complied by 1 September 2025, the associations plan to take legal action to enforce their obligation. Meanwhile last year in 2024, airline Vueling in Spain was fined €90,000 in for failing to make their website accessible. They were fined even before the EAA came into force, demonstrating that accessibility enforcement isn’t just theoretical, the EAA will only make expectations even clearer. Fashion Nova in the US was fined $5,150,000, individuals who are legally blind and attempted to access the Fashion Nova using screen reading software now may be eligible to submit a claim.  ( 5 min )

The difference often comes down to one word: liquidity. Liquidity pools don’t usually get the spotlight, but they are the real engine of a DEX. Without them, token swaps grind to a halt, traders get frustrated by slippage, and liquidity providers (LPs) have no reason to stick around. It’s like running a supermarket where half the shelves are empty, you can have the best lighting and catchy slogans, but if people can’t buy what they came for, they won’t come back. For anyone exploring decentralized exchange development, the design of your liquidity pools is where the success story really begins. What follows isn’t theory, it’s a practical blueprint that breaks down how to think about liquidity pools, how to design them, and what pitfalls to avoid.

Remember the last time you installed a CLI tool and it asked for your API key? You probably hunted through documentation, navigated to some settings page, generated a key, then carefully copied it into a config file. Now multiply that friction by every user of your tool. There's a better way, and it's been hiding in plain sight. API keys seem simple on the surface. Generate once, use forever. But that simplicity masks serious problems that compound as your tool gains adoption. First, there's the security nightmare. Users paste API keys into dotfiles, commit them to repositories, share them in documentation. Once leaked, an API key becomes a permanent liability — there's no way to know who has it or where it's been copied. Unlike passwords that users might change periodically, API keys tend…  ( 7 min )

WTF is this? API Gateway Pattern: The Unsung Hero of the Internet Hey there, tech-curious folks! Welcome to today's installment of "WTF is this?" where we demystify the confusing tech concepts that make you go. Today, we're tackling the API Gateway Pattern, a crucial piece of internet infrastructure that's often overlooked, yet utterly fascinating. What is API Gateway Pattern? Imagine you're at a fancy restaurant, and you want to order a delicious meal. But, instead of talking directly to the chef, you give your order to a friendly waiter. The waiter takes your request, translates it into chef-speak, and then delivers the dish back to you. That's roughly what an API Gateway does, but instead of food, it's handling requests and data between different systems. An API Gateway Pattern is a des…  ( 7 min )

Why You Might Want This Integration Whether you're coordinating a feature rollout or organizing a content sprint, keeping workflows smooth across tools like Jira (for engineering) and Asana (for planning) is essential.

Maintain consistency on due dates, statuses, and fields. Let each team work in their preferred tool, without constant context switching. Developers working in Jira can surface relevant tasks in Asana. Writers updating Asana tasks automatically push changes to Jira issues. Custom fields (like “estimated reading time” or “community feedback”) are preserved across platforms. Although Getint …  ( 6 min )

Background Two years of full-stack development experience, and a competitive programmer (Codeforces Master). Applied through Google Careers, but did not pass the referral process. Received a call from a recruiter during the first week of April, who asked about my background, experience, and salary expectations.

However, the actual interview dates were much later than the dates I provided. *Problem: * *Solution I gave: * Follow up · Why don't you trigger the increment in the get minimum call? · What is the real-world application of this problem? Why are we having an initial sequence number? · How do you identify the frames that are received but we are not able to process (corrupted)? · How do you distinguish between the corrupted ones and the ones that are being processed? Interview Process Round 1：Technical Interview My response: Follow up: Round 2：Technical Interview My response: Follow up: My response: 3 combinations: (a, b first meet, club and then meet d), (b, d first and then a), (d, a and then b). Iterate for each pair of possible joining points of the path for each combination and update the answer. (Did not implement) Round 3：Technical Interview Problem-2: Round 4：Technical Interview Recruiters indicated that they had received negative feedback in the first two rounds.

Beyond the 12 Factors: Portability While Portability is not one of the official 12 factors, it is a major outcome of following them correctly. The original 12 factors, defined by Heroku, are specific best practices for building modern, scalable applications. When applied together — especially principles like Config, Backing Services, and Dev/Prod Parity — they naturally lead to high portability. Infrastructure-agnostic: The app can run on different platforms or providers without changing the source code. Configuration-driven: Differences between environments are handled through environment variables and config files, not code changes. Standard interfaces: Using widely adopted protocols and services allows easier migration. Containerization: Packaging the app and its dependencies into a container ensures consistent behavior anywhere. Why It Matters Flexibility: Easily move between providers or environments. Cost efficiency: Switch to better pricing or features without rewriting code. Resilience: Simplifies disaster recovery by running the app in multiple regions or platforms. Future-proofing: Reduces the risk of vendor lock-in. Example A Python API service is packaged in a Docker image. That same image runs: On AWS ECS On Azure Container Apps On Google Cloud Run No source code changes are required — only environment configurations differ. Keep code independent of provider-specific APIs unless necessary. Store configuration outside the codebase. Use containerization or virtualization to maintain consistency. Test your app on multiple platforms. Avoid hardcoding infrastructure-specific details. Takeaway: Portability is the natural result of applying the 12-Factor principles. It gives your application the flexibility to run anywhere, adapt to change, and avoid being tied to a single provider.  ( 5 min )

Principle #12: Admin Processes Goal: Run administrative or maintenance tasks as one-off processes in the same environment as your application, using the same codebase and configuration. One-off tasks: Admin processes are temporary jobs such as database migrations, data cleanup, or maintenance scripts. Same environment: These tasks should run in the same environment and with the same configuration as the app, ensuring consistency. Use app's code: Reuse existing application code for admin tasks instead of creating separate scripts with their own logic. Ephemeral: Admin processes are short-lived and not part of the regular running services. Why It Matters Consistency: Ensures admin tasks behave exactly like the application in production. Reliability: Reduces the risk of environment-specific bugs. Efficiency: Reuses tested and maintained code instead of duplicating logic. Safety: Runs in a controlled environment, lowering the chance of introducing errors. Example A Rails application needs to update its database schema: The developer runs rake db:migrate in the production environment. The command uses the same database connection settings and code as the live application. Once the migration finishes, the process exits. Best Practices Run admin processes as separate, short-lived jobs. Use the same environment variables and configurations as the app. Reuse application code for consistent behavior. Keep admin scripts version-controlled with the app. Ensure admin tasks can be run on-demand without special setup. Takeaway: Treat admin processes as one-off tasks that run in the same environment and with the same code as the application, ensuring consistent, reliable, and safe operations.  ( 5 min )

Principle #11: Logs Goal: Treat logs as event streams that are written to standard output, and let external tools handle storage, analysis, and archiving. Event streams: Logs should be a continuous, ordered flow of event data that describes what's happening inside the app. No log files: The app itself shouldn't manage or store log files. Instead, write logs to stdout or stderr. External aggregation: Use log management systems to collect, store, and analyze logs from multiple instances. Real-time access: Logs should be viewable in real-time to help diagnose issues quickly. Why It Matters Centralized monitoring: Makes it easier to search, analyze, and correlate logs from different parts of the system. Scalability: Works well in distributed systems where multiple instances are generating logs. Troubleshooting: Real-time log streams help in quickly identifying and fixing problems. Portability: No dependence on local storage or specific server setups. Example A Node.js app writes logs to stdout. In production, a service like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk collects and stores these logs. Developers and operations teams can search logs, create dashboards, and set alerts without changing the app's code. Always write logs to standard output. Use structured logging (e.g., JSON) for easier parsing. Keep logs free of sensitive information. Integrate with centralized log management tools. Use log levels (info, warn, error) consistently. Takeaway: Treat logs as real-time event streams, send them to external systems for processing, and keep your application stateless and portable.  ( 5 min )

Principle #10: Dev/Prod Parity Goal: Keep development, staging, and production environments as similar as possible to reduce the risk of issues when deploying. Minimize differences: Ensure the tools, dependencies, and configurations match across all environments. Frequent deployments: Push code changes to production regularly so the gap between development and production is small. Same tooling: Use the same databases, libraries, and build processes everywhere. Collaborative approach: Development and operations teams work closely to maintain parity. Why It Matters Fewer surprises: If environments are similar, bugs that appear in production are more likely to be caught in earlier stages. Consistent performance: The app behaves the same way in testing as it does live. Faster debugging: Issues can be reproduced and fixed more easily. Smoother deployments: Reduces the complexity and risk of moving code to production. Example A SaaS product uses Docker for all environments: Developers run the same Docker image locally as in production. Staging and production use identical build pipelines and dependencies. Environment variables configure differences such as database URLs, but the software itself is identical. Best Practices Use containerization to match environments. Keep staging and production as close as possible in setup and data. Deploy to production often to reduce the delta. Share configuration management tools across environments. Automate environment setup to avoid human error. Takeaway: The closer development, staging, and production are, the fewer surprises you'll encounter at deployment time, leading to smoother, more reliable releases.  ( 5 min )

When building backend applications in JavaScript/TypeScript, two names come up repeatedly: Express.js and NestJS. Express is minimal, flexible, and lightning-fast to get started. NestJS builds on top of Express (or Fastify) but enforces structure, scalability, and maintainability. So, which one should you choose for your next project in 2025? Let’s dive deep. Express is essentially unopinionated. You can structure your project however you like. This is amazing for small projects but can get messy as your app grows. 👉 Example: A simple route in Express: // server.js const express = require("express"); const app = express(); app.get("/users", (req, res) => { res.send("List of users"); }); app.listen(3000, () => { console.log("Server running on port 3000"); }); ✅ Quick to set up NestJ…  ( 7 min )

When ChatGPT first started making waves, I was skeptical. I figured it was another shiny tech fad that might be fun to play with, but wouldn't really stick in my day-to-day work. Fast forward, and now I can't imagine programming without some form of AI in my toolkit. I'm not saying AI has replaced my skills, far from it. But it has reshaped how I approach problems, especially the boring, repetitive, or purely mechanical parts of development. Here's what that looks like from my side of the keyboard. If you've been coding long enough, you know the "classic" dev cycle: Plan: Define the problem, sketch out solutions, argue with teammates on naming conventions.

When we started in 2023, our mission was simple: help businesses build with AI. Our first product was a fine-tuning tool for businesses to customise AI models. At the time, fine-tuning was resource-heavy & challenging. Fine-tuning required preparing datasets (and even synthetic data generation was not as highly feasible as today), running heavy compute, and testing multiple iterations to avoid issues like overfitting or underfitting. In practice, this meant months of work and high costs—something only big tech firms could manage. We saw this gap. Instead of making everyone rebuild models, we introduced advanced RAG-based AI chatbots that could train on a company’s own data while using existing models. RAG allowed companies to use powerful existing models while still grounding answers in th…  ( 6 min )

Much like many folks I have been vibe coding whatever ideas come to mind for fun, to learn and to just work through things. I participated in a hackerthon in July and my initial idea was sports related. As I started building I remembered that I needed to add GDPR compliance aspects, cookie policy and cookie popup. This ended up being my hackerthon submission. A tool that scans a website to establish the context, and takes in 2 input from the user - region and industry. Using a multimodel approach I assess the website for data privacy compliance and give a score and explanation on what is missing and why it is a problem. The next step is to help generate the requirements to help one meet the minimum requirements by generating the context aware cookie policy, privacy policy, cookie popup/modal and the terms of use. The output is easy to read, and comes in downloadable code form too. It made me wonder, how many people are vibecoding and don't know that they need to consider data privacy laws and regulation for their audience and location?  ( 5 min )

In the complex landscape of B2B tech sales, marketing strategies must do more than just attract attention—they must educate, build trust, and guide decision-makers through a multifaceted buying journey.

In today’s digital landscape, short-form video has become the dominant way people consume content. Platforms like TikTok, Instagram Reels, and YouTube Shorts thrive on quick, engaging clips. As a creator who occasionally experiments with content, I wanted to see if AI tools could really simplify the editing process. That’s how I came across Short AI, an AI Clip Maker designed to help transform long videos into snackable highlights. After spending some time with it, here are my impressions. Short AI Editing videos can be time-consuming, especially when the goal is to repurpose long-form content into short, engaging clips. I’ve often struggled with trimming hours of recordings into something worth sharing on social platforms. The promise of a tool like Short AI is that it takes away much of that manual work by letting AI handle the heavy lifting. After testing the platform, these are the features that stood out to me: The workflow is straightforward: Saves Time: I didn’t have to scrub through hours of footage. AI Judgment Isn’t Perfect: Sometimes the highlighted clips weren’t the ones I’d personally choose, so manual adjustment was still needed. Based on my experience, I think Short AI could work well for: Overall, my time with Short AI was positive. It won’t completely replace manual editing for those who want fine-tuned control, but as a quick way to create engaging short clips, it’s surprisingly effective. The balance between automation and customization makes it useful for creators who want to keep up with short-form video trends without spending hours editing. Short AI.  ( 7 min )

👀 Question: What do you think this code prints when it runs? function callNextTick() { console.log("This is a weird code");` Expected Behavior (Without nextTick) Normally, the event loop processes tasks in phases: Timers Phase → Executes setTimeout (even with 0ms delay). Check Phase → Executes setImmediate. But here, both setTimeout and setImmediate will never get a chance to execute. Why is that? Understanding process.nextTick() Unlike setTimeout or setImmediate, process.nextTick() is not part of the normal event loop phases. It has its own special queue called the nextTickQueue. Callbacks in this queue run right after the current code finishes, before the event loop moves to any phase. How the Code Executes Step by Step 1.setTimeout(() => { console.log("time out") }, 0) is scheduled for the timers phase. The synchronous line console.log("This is a weird code") executes. Node checks the nextTick queue after the current code finishes. callNextTick runs from the nextTick queue. Inside callNextTick, process.nextTick(callNextTick) schedules itself again. Steps 6–8 repeat infinitely, because nextTick always runs before the event loop moves to any phase. Result: The event loop never reaches timers, I/O, or check phases, so setTimeout and setImmediate callbacks are never executed. This is called starving the event loop or blocking the event loop. Key Takeaways ✅ nextTick is not part of the event loop → It runs before the loop proceeds. ✅ Recursive nextTick = Event Loop Blockage → Starves timers, I/O, and setImmediate. ✅ Avoid nextTick recursion → Use setImmediate if you need to defer execution without blocking.  ( 6 min )

Stakeholder Identification The first step in developing a stakeholder management plan is to identify all individuals or groups who may influence—or be influenced by—the project. This process often starts with internal brainstorming sessions among the project team and sponsor. Team members examine organizational charts to capture all relevant departments and reporting lines, which helps reveal stakeholders who may not be immediately visible. In addition, contract documents and project charters should be reviewed to identify external parties such as suppliers, clients, subcontractors, and regulatory agencies. For more complex projects, consulting with subject matter experts can be essential, since they often have practical knowledge about stakeholders who are not listed on formal documents…  ( 6 min )

A Virtual Machine Scale Set (VMSS) is an Azure compute resource that lets you deploy and manage a group of identical, load-balanced virtual machines that can automatically scale in or out based on demand. Instead of manually creating and managing multiple VMs for your application, you create one VM template, and Azure automatically clones, monitors, and scales it for you. They are collection of identical virtual machines that are automatically managed or scaled together. We have got Horizontal scaling which is scaling out and scaling in, in other words increasing and decreasing of your virtual machines and vertical scaling is scaling up and down, increasing and decreasing the CPU,RAM etc. To create a virtual machine scale set, in this article we need to create a virtual machine, using win…  ( 9 min )

This article is created by Logto, an open-source solution that helps developers implement secure auth in minutes instead of months. The software development world is flooded with "AI agents" in 2025. Most promise to write your code, finish your tasks, and ship your app while you sleep. The reality? Some are noise. A few are signal. But a handful of tools actually deliver real leverage. They fit into your workflow, take things off your plate, and help you build faster, especially when you're short on time or context switching too much. These aren't just copilots or chatbots. They're hands-on agents that help you move from vague ideas to working software. Good coding agents don't just autocomplete. They understand context, work across files, and integrate into how you actually build softwar…  ( 12 min )

Ten years ago, getting into tech often meant expensive computers, pricey software, and years of formal study. AI was still in research labs, cloud computing was just catching on, and smartphones, though impressive, weren’t the portable creative powerhouses they are today. Fast forward to now: AI tools can generate code, design interfaces, and write content in seconds. You can learn a programming language entirely from free online videos. You can collaborate with a global team without leaving your bedroom. The future? Expect AI-driven automation, VR/AR workspaces, and even quantum computing as part of everyday workflows. The demand for people who can build, adapt, and innovate will keep growing, and you don’t need a CS degree to be part of it. Lower entry barriers than ever before Start cod…  ( 7 min )

Your UI might be lightning fast under the hood… but does it stay smooth when things get busy? Imagine this: you’re scrolling through a giant online catalog. You type in the search bar — the letters appear instantly (phew ✅), but the giant product grid lags slightly behind. Instead of freezing the whole page, the search results play catch-up gracefully. That’s the power of React’s useDeferredValue. It doesn’t speed up your code — it helps your app stay responsive by letting some parts of the UI “wait a beat” while more urgent updates flow through. If useTransition is React’s way of saying “do this now, do that later”, then useDeferredValue is React’s way of saying: “Here, take your time with this value — I’ll keep showing the old one until the new one’s ready.” In this article, we’ll break …  ( 13 min )

Your app might be fast… but does it feel fast? Picture this: you’re typing into a search box, and suddenly your app feels like it’s running on a potato computer. 🥔💻 Letters appear a split-second late. The dropdown lags. The fan sounds like it’s about to take off. Technically, your app is still doing its job… but to the user, it feels sluggish and broken. That’s the subtle killer of UX: not speed, but perceived speed. And that’s where React 19’s concurrency features — startTransition and useTransition — step in. Do they make your code faster? Nope. Do they make your app feel smoother and more delightful? Oh yes. By letting urgent updates (typing, clicks, drags) happen instantly while heavier work (filters, charts, big renders) runs “in the background,” concurrency makes your UI b…  ( 18 min )

Before We Dive In… When React first showed up (2013 era), it was proudly a client-side library. The browser was its home turf. You’d load React, it would grab a root div, and bam — your UI would spring to life right there in the client. That was the magic: move fast, no server templates, just JavaScript. But as apps got bigger, the cracks started to show: Users had to download huge JavaScript bundles before seeing anything. Slow devices struggled because they had to do all the rendering work. SEO wasn’t great, since search engines saw empty before React hydrated. To fix this, React introduced server-side rendering (SSR). The idea: instead of making the browser build the first page, the server does it and sends ready-to-display HTML. That way, users saw something fas…  ( 20 min )

Vue.js is one of the most popular front-end frameworks today, prized for its simplicity, reactivity, and component-based architecture. At the heart of Vue’s declarative style lie directives—special tokens in the markup that tell Vue how to reactively manipulate the DOM. If you’re building Vue applications, understanding directives is essential for creating dynamic, responsive interfaces. Enjoy! In Vue, a directive is a special attribute prefixed with v- that provides reactive behavior to DOM elements. Unlike plain HTML attributes, directives can react to changes in your application’s state and update the view automatically. For example: Hello, Vue! Here, v-if is a directive that conditionally renders the paragraph element based on the value of isVisible. Vue provi…  ( 9 min )

AI art is everywhere these days. Type in a prompt, and boom. You’ve got a “masterpiece” in seconds. It feels magical, but also… kind of wrong. And as programmers, I think we should step back and ask ourselves: is this really the kind of creativity we want to support? Because if anyone understands what it means to create, it’s us. People outside our world often think coding is just math and rules; cold, logical, robotic. But you and I know that’s not true. Writing good code feels a lot like writing poetry, painting, or composing music. Because, it is just that. We agonize over function names like a poet over word choice. We refactor messy blocks of logic the same way a sculptor chips away at stone. We structure systems so they’re elegant, not just functional, like a designer shaping form an…  ( 6 min )

Python is an easy-to-learn, powerful programming language. One of the fundamental concepts every beginner should master is how variables work and the different data types available in Python. A variable stores data that your program can use, modify, or display. In Python, you don't have to declare the type of a variable explicitly. Python figures it out when you assign a value. # Assigning values name = "Alice" age = 25 temperature = 36.6 String (str) Text data. Enclosed in single or double quotes. greeting = "Hello, world!" Integer (int) Whole numbers. count = 42 Float (float) Numbers with decimals. pi = 3.14159 Boolean (bool) Logical values: True or False. is_active = True List Ordered, changeable collection of items. fruits = ["apple", "banana", "cherry"] Dictionary (dict) Key-value pairs. student = {"name": "Bob", "age": 20} Python lets you change the type of a variable any time: x = 5 # x is initially an integer x = "five" # now x is a string Conclusion Understanding variables and data types is essential for writing effective Python programs. Practice by creating variables of different types and experimenting with them!  ( 6 min )

I originally posted this post on my blog a long time ago in a galaxy far, far away. I don't have a coding portfolio. I've never had one. By portfolio, I mean a webpage showcasing my best projects. My GitHub account is the closest thing to a coding portfolio. But it hasn't helped me land jobs. My blog and writing online have helped me more. Here's how: Some time ago, the next day after interviewing for a small local company, I got a phone call. They wanted me to start a company blog for them. The interviewer read some of my blog posts. I had a link to it on my CV. He wanted me to write something similar for them. I wrote five blog posts for them with interview preparation material. Even though I decided not to continue the interview process, I declared it a win. Also, I made some lunch money with them. Years later, the last time I applied for a job, in the first interview, I shared my screen and walked the interviewer through my blog. The interviewer asked if I contributed somehow to the coding community. The process went smoother from there. I didn't have any coding interview after that, except for opening a PR on an open source project. That was it. Sharing your thoughts and learnings can open unexpected doors. Even if you don't land new jobs, you'll learn new skills. And more importantly, you'll learn to think better. So write your first online piece or your first TIL post, and see what opportunities it brings. Starting out or already on the software engineering journey? Join my free 7-day email course where I share the lessons I've learned from 10 years in software engineering, so you can skip the trial and error and move your career forward.  ( 6 min )

When AI Chatbots Turn Into Money Furnaces Picture this: You've built a brilliant AI chatbot handling 1,000 requests per second. Users love it, everything seems perfect. Then you check your GPU bill and nearly choke on your coffee - $50K for the month, and it's only the 15th. Your "efficient" AI system is actually a digital money furnace, burning through compute resources faster than a teenager burns through their phone battery. The culprit? Your chatbot suffers from computational amnesia, reprocessing nearly identical questions over and over again. Every time someone asks "What's your refund policy?", your system burns through 2,500 tokens of expensive context processing. When the next user asks "How do I get my money back?" - essentially the same question - your system treats it a…  ( 9 min )

At first, I thought this would be a minor problem. There are so many tools and browser tricks available online, it felt like I would find a quick fix. But the reality was very different. Some tools exported only part of the file, losing entire pages or images. Others had strict limits, working only for 20 pages at a time. Imagine doing that for a 700-page file. The worst ones required me to manually scro…  ( 7 min )

In this article, I'll share my experience building a document-aware chat system using Supavec and Gaia, complete with code examples and practical insights. Every developer who has tried to build a document Q&A system knows the pain points: Complex document processing pipelines Managing chunking and embeddings Implementing efficient vector search Maintaining context across conversations Handling multiple file formats The breakthrough came when I discovered the power of combining two specialized tools: Supavec: Handles document processing infrastructure Gaia: Provides advanced language understanding Here's a comparison of the traditional approach versus using Supavec: // Traditional approach - complex and error-prone const processDocumentTraditional = async (file) => { const text = await e…  ( 7 min )

A slow Shopify store is more than an inconvenience. It directly impacts user experience, search engine rankings, and sales. Customers expect pages to load quickly, and if they do not, bounce rates increase and conversions drop. For developers, improving performance means going beyond design and diving into code, theme structure, and optimization techniques. In this article, we will break down common causes of slow Shopify stores and provide actionable tips to make them faster and more efficient. If you need expert help with optimization or custom Shopify development, you can also explore Harbor Sourcing. Before making changes, run a performance audit to identify what is slowing down the store. Tools such as Google PageSpeed Insights, Lighthouse, and GTmetrix are excellent for spotting issu…  ( 6 min )

I’ve shipped a small, focused UI component for modern Angular apps: an international telephone input with country flags, dropdown, and real validation/formatting. It wraps the excellent intl-tel-input for UI and libphonenumber-js for validation/parsing, and exposes a clean Angular API that works with Reactive & Template-driven Forms (CVA). It emits E.164 numbers by default (e.g. +14155550123), and is SSR-safe. TL;DR ✅ UI via intl-tel-input, rules via libphonenumber-js ✅ Emits clean E.164 values ✅ Works with Reactive & Template forms (ControlValueAccessor) ✅ Angular 17–19, standalone, SSR-friendly ✅ Options: separateDialCode, nationalMode, preferredCountries, attach dropdown to , sizes, variants, clear button, autofocus, select-on-focus 🌍 Localization & RTL: customize labels, country n…  ( 7 min )

This article was originally published on my website, screensizechecker.com. You can find a full suite of free developer tools and more in-depth articles there. It looks perfect on your 27-inch monitor, but it's a disaster on your phone. We've all been there. You've spent hours crafting what you thought was a bulletproof responsive design, only to discover that your carefully planned layout crumbles the moment someone views it on a different device. The navigation overlaps the content, images spill out of their containers, and text becomes unreadable. Sound familiar? After over a decade of debugging responsive layouts for high-traffic websites, I've seen every possible way a design can break—and more importantly, I've developed a systematic approach to fix them quickly. The random CSS prope…  ( 14 min )

Imagine you’ve just set up a brand-new laptop. You’re excited, coffee in hand ☕️, ready to code. But before you can write even a single line, you need your toolkit — Git, Node.js, Python, Docker, VS Code. Now comes the ancient developer’s question: 👉 “Should I download them one by one… or is there a magical tool that installs everything for me?” That magical tool is called a package manager. And in this article, we’ll walk through the developer-friendly package managers across Windows, macOS, and Linux distros, with a story-like journey and step-by-step guides. Linux has had package managers since forever. That’s why it’s often called the “wise old grandparent” of developer tooling. Depending on your Linux distro: Debian/Ubuntu → apt sudo apt update sudo apt install git sudo apt install p…  ( 7 min )

🧨 Wornmaxing for Devs: Why Your Old Laptop Is the Ultimate Coding Playground Wornmaxing isn’t about minimalism—it’s about maximal abuse. It’s the art of pushing old tech past its limits, not because it’s efficient, but because it’s liberating. If you’ve got an 11-year-old laptop with a leaky battery and a cracked screen, congratulations: you own the perfect guinea pig for your wildest dev experiments. Fearless Installation: You don’t worry about breaking things. You install, uninstall, and reinstall like a mad scientist. Zero Guilt: If it crashes, you laugh. If it overheats, you open a window. If it dies, you salute it. Creative Recklessness: You treat your machine like a sketchpad, not a showroom. Here’s what makes an old laptop a dev’s best friend: Install Local LLMs: Try running lightweight language models like LM Studio or Ollama. You’ll learn more from the struggle than from a plug-and-play cloud API. Test IDEs & Dev Environments: VS Code, Neovim, JetBrains IDEs—go ahead and install them all. Break your config. Rebuild it. Repeat. Language Pack Chaos: Want to play Japanese visual novels or retro games? Install obscure language packs, font renderers, and input methods. It’s a rabbit hole worth diving into. Run Sketchy Scripts: Found a weird GitHub repo with no documentation and a warning about “use at your own risk”? Perfect. Clone it and see what happens. You Learn More: When things go wrong, you actually understand your stack. You Get Bold: You stop fearing errors and start embracing them. You Build Grit: Wornmaxing teaches resilience, not just syntax. Your old laptop isn’t obsolete—it’s unleashed. It’s the perfect platform for reckless creativity, fearless experimentation, and deep learning through chaos. So stop babying your gear. Start wornmaxing.  ( 6 min )

This article was originally published on my personal blog on 2025/08/13 Hiee! Welcome to another post where I'm going to show you how we can use Knip to declutter our TypeScript and JavaScript projects. Knip is an amazing tool that aims to declutter your JavaScript and TypeScript projects. But what does decluttering mean? If you've ever worked on a project for a while that involves a bunch of people or even just yourself, you'll notice that unused code and dependencies tend to accumulate in the codebase over time. This is also known as Technical Debt. Technical Debt is the mess no one on your team wants to touch. Oh wait, that sounds a bit too vague. Here's a better one: Technical Debt can be anything from legacy code that might just be hanging by a thread or might be craving for a refacto…  ( 8 min )

This article was originally published on my personal blog on 2025/06/14 Hie! Welcome to another post where I'm going to use my poor writing skills to simplify Git for you, XD. If you're reading this, I expect you to be already familiar with the basic Git workflow. Git is often portrayed as overly complex, which it is but only if you consider all the features it has to offer. If you only consider the features that you need for everyday software development, it becomes much simpler to use in practice. Having worked at various companies and multiple personal projects over the years, one thing that has been constant is Git. Your tech stack might change every year or so, but Git remains the same. Learn it once, and you can use it everywhere. While I'm not an expert, I'll walk you through the mo…  ( 10 min )

This article was originally published on my personal blog on 2025/01/28 If you're reading this, you've probably worked with promises before. And when I say promises, I don't mean the ones made by your friend or partner. Most of the time, they're API calls on the client or database queries on the server—basically, anything async in JavaScript. I can’t fathom how many codebases out there are littered with code like this. Let’s look at an example that uses sequential execution to understand what the problem is. Here’s a function that gets the user data — it’s highly abstracted for simplicity. async function getUserData(userId: string): Promise { const posts = await getPosts(userId); // 1000ms const followers = await getFollowers(userId); // 1000ms const following = await getFo…  ( 8 min )

This post is my submission for DEV Education Track: Build Apps with Google AI Studio. Have you ever stumbled across a promising startup's website, only to find it filled with generic stock photos and placeholder logos? Or maybe you're a developer who's brilliant at backend code but struggles with visual design? What if there was a way to instantly transform any website's visuals with AI-generated images that actually belong there? That's how WebImgs was born – a Chrome extension that scans any website, understands its design DNA, and regenerates every visual asset to match perfectly. No more mismatched stock photos or bland placeholders. Just click, scan, and watch a website come to life. WebImgs isn't just another AI image generator – it's a design detective. Here's what makes it special:…  ( 8 min )

How Flutter Builds and Updates Your UI (Explained Simply) If you’ve used Flutter for a while, you know how fun it is to compose widgets and get instant results on screen. But behind that smooth developer experience, Flutter’s engine is doing a ton of work every frame to keep things responsive and fast. This post is a walkthrough of what really happens when you write something as simple as: Scaffold( appBar: AppBar(title: Text('Hello Flutter')), body: Center( child: Text('Welcome!'), ), ); We’ll unpack how Flutter turns that into pixels, how it decides what needs to rebuild, and how you can use this knowledge to debug or optimize your apps. Whether you’re just starting out or have a decade of experience in UI frameworks, this will give you a clear mental model of Flutter’s rend…  ( 8 min )

If you’ve spent any time looking into Microsoft Dynamics 365, you’ve probably come across this question: Is Dynamics 365 CE an ERP system? The short answer is no. Dynamics 365 CE (Customer Engagement) is Microsoft’s CRM system, built to help organisations manage relationships and interactions with their customers. It includes applications such as: Sales – managing leads, opportunities, and deals Customer Service – handling cases and support requests Field Service – scheduling technicians and managing assets Project Operations – tracking project delivery and billing In simple terms, CE acts as the “front office” — the part of your business that customers see and interact with. ERP, or Enterprise Resource Planning, is designed to run the core operations of a business. This covers areas such as: Finance and accounting Supply chain and inventory Procurement Manufacturing HR and payroll In the Microsoft world, ERP capabilities are delivered through: Dynamics 365 Finance Dynamics 365 Supply Chain Management Dynamics 365 Business Central (for small and medium-sized businesses) ERP is the “back office” — ensuring processes, resources, and finances run smoothly behind the scenes. A Simple Analogy Think of your business as a restaurant. Dynamics 365 CE is the front-of-house team — greeting customers, taking orders, and making sure the experience feels seamless. On its own, CE isn’t ERP. CE manages customer interactions, while ERP looks after the operational side. When combined, they form a complete system from end to end. CE (CRM) manages the customer-facing processes. ERP manages operational and financial processes. Together, they provide visibility from the customer’s first interaction all the way through to the final invoice. So, is Dynamics 365 CE an ERP? Not on its own. But when paired with Microsoft’s ERP applications, it gives you the full picture.  ( 6 min )

I have three years of experience in Java backend development. I took advantage of the national subsidy to buy a MacBook Pro with 32GB and 1TB of RAM over the last weekend. I'd like to ask developers how to develop elegantly on a Mac. For example, I don't want to install many databases (MySQL (5.7/8.0+), PostgreSQL, etc.) and multiple runtime environments (Java, Python, Go, Node (I only know Java, and I'm not very good at other things. I want to learn more about them later)) on my mac. How can I keep my mac relatively clean? I don't want it to be as messy as on Windows (I have a slight obsessive-compulsive disorder). I also welcome your suggestions for useful tools (for development/entertainment, etc.). I'd be very grateful.  ( 5 min )

Hey folks, This week, after careful consideration and a lot of back and forth, I've decided to pivot again, to a hybrid combat system that uses both Attributes and Skill-Based Progression. I'm drawing on a lot of inspiration from Dark Souls for my Attribute and weapon scaling components, but I'm going to move forward with a skill system that requires players to equip weapons to earn progress with their skills associated with them. For example, a long sword defines its base damage, attack speed, range, attribute requirements and how the damage scales with each attribute. The "Swords Proficiency" skill applies to any sword the character equips, and determines their Accuracy, Crit Chance, Crit Damage and Armour Penetration scale with skill ranks. The more Expeditions and Combats that the character completes, the more experience they get towards ranking up the skills supporting their equipped weapons and spells. For anyone that is interested, I've set up a roadmap on Github here. I'd welcome any comments or feedback people have on this or any of my previous blogs, and please feel free to follow my socials and dev blogs, or join my Discord community. Details on all that can be found at magipunk.com. Cheers! Dan Dahl  ( 5 min )

.trivyignore is a configuration file used by Trivy, an open-source vulnerability scanner for containers, Kubernetes, and other dependencies. 🔹 Containers Its dependencies (libraries, runtimes like Node.js, Python, Java, etc.) 👉 Think of it like a zip file that has everything your app needs so it runs the same way on any machine. 🔹 Kubernetes (K8s)3 With Kubernetes: You describe what you want (e.g., "I need 5 containers of my RN backend always running"). Kubernetes automatically deploys, scales, heals, and load-balances containers. 👉 Think of it like a container orchestrator or a "manager for containers." 📌 Example: You write a YAML file (deployment.yaml) that says: Run 5 replicas of my RN backend container. Expose them via a service on port 3000. Kubernetes ensures those 5 are always running. If one dies → it restarts it. Container = a package of your app + everything it needs to run. What is Trivy? OS package vulnerabilities (e.g., in Alpine, Debian, Ubuntu) Application dependencies vulnerabilities (e.g., npm, pip, Maven) Container image vulnerabilities Infrastructure as Code (IaC) misconfigurations What is .trivyignore? Acknowledge a vulnerability but determine it doesn’t affect your project. Are waiting for an upstream fix and want to suppress noise. Need to whitelist known issues for compliance reasons. How to use .trivyignore? Create a .trivyignore file in your project root. Add the vulnerability IDs you want to ignore. CVE-2022-1234 CVE-2021-5678 Trivy will skip reporting these vulnerabilities in scans.  ( 6 min )

In the previous blog posts, I discussed state management and how it works with useState. In this post, I'll cover useReducer and how to manage state in React. What is a Reducer? Why do we use it? How Reducer Works What is a Reducer? reducer is a function used with the useReducer hook, which needs to be imported at the top of your file. const [state, dispatch] = useReducer(reducer, initialArg, init?) Why do we use it? useState and useReducer are similar in functionality, useReducer can make our code easier to handle. By using a reducer, we can create a separate file that contains only the reducer function instead of writing it in each component. This reduces the amount of code within individual components, which is one of the reasons why it is called a "reducer." How Reducer Works useState…  ( 7 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My fascination with routing systems began during a web development internship where I witnessed firsthand how poor routing design can cripple application performance. Our legacy system used a massive switch statement with hundreds of hardcoded routes, making it nearly impossible to maintain and scale. This experience drove me to explore modern routing architectures that could handle complex URL patterns while maintaining exceptional performance. The revelation came when I discovered that most web frameworks treat routing as an afterthought, implementing naive linear search algorithms that degrade performance as route complexity increases. My research led me to a framework that implements sophisticated routing algorithms capable of…  ( 11 min )

Migrating or syncing data between PostgreSQL databases is a common task for developers. Whether consolidating user data, archiving old records, or migrating production data to a reporting database, having a reliable and simple method can save hours of headaches. PostgreSQL’s dblink extension makes this process straightforward, allowing you to query one database from another as if the two were connected tables. Before using dblink, you need to make sure the extension is created in your target database: CREATE EXTENSION IF NOT EXISTS dblink; This only needs to be done once per database. After that, you can safely use dblink to query other PostgreSQL databases. Imagine you have: Source database: user_data_archive Target database: user_data_main Target table: users The users table has un…  ( 6 min )

Ever had an application that slowly, almost imperceptibly, starts consuming more and more memory, until one day it just... crashes? You check your code, everything looks fine, no obvious memory leaks. But what if the culprit is hiding in plain sight, in a tool you thought was helping you manage thread-specific data? We're talking about ThreadLocal. ThreadLocal is a fantastic tool. It lets you store data that's unique to a specific thread. Imagine you're building a web application. Each user request comes in on a different thread. You might want to store information like the current user's ID, their transaction details, or a database connection that's specific to that request, without passing it through every single method call. ThreadLocal makes this super easy. It acts like a private lock…  ( 9 min )

GitHub Homepage As a junior computer science student, I gradually recognized the importance of asynchronous programming during my web development learning process.

Let's talk about the resume. You've seen a million of them. I've sent a million of them. It usually starts with a document that looks something like this: A beautiful piece of paper, right? 📜 It's packed with keywords, meticulously formatted, and tells you one thing with absolute certainty: I know how to use Google Docs. But then comes the real fun... the ancient ritual of "The Interview." It's a heroic journey. Our brave candidate, Sir Stickman, battles mythical beasts on his noble quest for employment. You know the story. He fights the Dragon of Unforeseen Traffic 🚗💥, narrowly dodges the Meteor of Spilled Coffee ☕, and vanquishes the Goblin of Crippling Self-Doubt. All of this, just to sit in a chair and try to convince you he's the perfect fit based on a 30-minute conversation. It's... a bit broken, isn't it? This is me. Right here. This is my natural habitat. This is where I'm not fighting traffic; I'm building solutions. I'm not trying to remember the "5 greatest weaknesses" I rehearsed; I'm solving actual problems. This is what I love to do. So I asked myself: Why am I trying to tell you I'm a skilled AI/Prompt Engineer on a piece of paper, when I can just show you? I decided to do the resume thing my own way. I built a resume that is the skill demonstration. A resume designed for the people I want to work with. A resume that proves my prowess before you even read the first line. Ladies and gentlemen, I give you... my resume. Game over. Mic drop. 🎤 If you're looking for someone who fits neatly into a Word template, I might not be your guy.

Lately I’ve been diving deep into the world of QR codes (yes, I know, not the sexiest tech topic 😅). One thing I’ve noticed: a lot of services make it really confusing. You generate a QR, then months later you find out it’s expired, locked behind a paywall, or you’ve lost control of the redirect. I’m curious: for your projects or businesses, do you prefer static QR codes (permanent, free, unchangeable) or dynamic ones (redirectable, but usually managed by a service)? Personally, I’ve been working on a little side project, hrefs.eu , that lets you do both: Static codes: free forever, never expire Dynamic codes: you control the redirect, no lock-ins But I’d love to hear from this community: Do you even use QR codes in your projects? If yes, which type do you find more useful? What’s your biggest pain point with them? Let’s discuss! I think there’s more nuance to QR codes than people give them credit for.  ( 5 min )

AI in 2025. Some say it will take our jobs. Some say it will replace developers entirely. lol And yes… the pace of AI tools can feel intimidating. But here’s the truth: AI doesn’t replace your thinking, it amplifies it. The real question in 2025 isn’t: “Will AI take my job?” Here’s what I consider when picking a stack today: Future-Proof Languages: TypeScript, Rust, Go strong ecosystems, growing community. Flexible Backends: Node.js/Deno for quick prototyping, Go/Rust for performance-critical apps. Databases That Scale: Postgres, MongoDB, or serverless-ready options like Supabase. AI-First Integration: Pick tools/libraries that allow AI integration without rewriting everything. Community & Support: A strong community means help is always a message away. Pro Tip: Don’t chase the “hottest stack” just because it’s trending. Focus on learning how to learn , In 2025, the smartest move isn’t avoiding AI . it’s choosing a stack that works with AI, not against it.

Docker is more than just a container runtime. Understanding its architecture is crucial for DevOps engineers to build scalable, secure, and automated deployment pipelines. What is Docker? At its core, Docker is a containerization platform that allows applications to run in isolated environments called containers. Unlike VMs, containers share the host OS kernel but still provide complete isolation of processes, networking, and filesystem. DevOps relevance: Eliminates “works on my machine” issues. Enables microservices deployment with consistent environments. Simplifies CI/CD pipelines, monitoring, and scaling. Core Components of Docker: a) Docker Engine Docker Daemon (dockerd): Background service running on the host. Handles building, running, and managing containers. Manages networks, volu…  ( 7 min )

This week we are diving back into Skillcrush 105 and getting to know the command line a little bit more. Your workspace is ready to go so it is time to start learning the basics of the command line. Keep in mind some of these commands will differ depending on what computer you are using and that's ok. I'll be talking about the PC commands in this post, but I will mention some of the commands Mac users can use. This post introduces directories and files. The most important thing Skillcrush students learned about in this lesson is how they work, how to create them, and how to switch between two different directories. Folders are great tools for both in real life and on the web. Developers love folders because they provide a good structure for their content. For example, when you build a por…  ( 10 min )

🔹 Introduction If you have written JavaScript for a while, you’ve surely faced one of the most common challenges: 👉 distinguishing between null, undefined, empty strings, zero, or other "falsy" values. It can be confusing, since JavaScript has its own truthy/falsy evaluation system. Sometimes you only need to check whether a variable exists, but in other cases you must know whether it is specifically null, undefined, "", or even an empty object or array. This article provides a comprehensive cheatsheet to cover all these scenarios, with explanations, code snippets, and practical use cases. Save it as your personal reference when debugging or writing clean conditions in JavaScript. In JavaScript, values are evaluated in Boolean contexts as either truthy or falsy. false): false…  ( 7 min )

GitHub Homepage During my junior year studies, I have been pondering a question: how can we optimize server architecture to the extreme while maintaining functional completeness? Traditional heavyweight frameworks, while feature-rich, often come with issues like high resource consumption and slow startup times. Recently, I encountered an impressive lightweight server architecture that completely changed my understanding of web server design. In my previous project experience, I have used mainstream frameworks like Spring Boot and Django. While these frameworks are powerful, their resource consumption left a deep impression on me. A simple Spring Boot application requires over 200MB of memory to start and often takes more than 10 seconds to boot up. // Traditional Spring Boot application st…  ( 10 min )

I did not post last week as I did not have much time to work on BST. I will keep this brief as my note-keeping was not ideal this week - something to improve. The LevelOrderForEach method The preOrder, inOrder and postOrder methods The Height method The Depth method the isBalanced method The reBalance method (currently half-working, but need to finish off) I am still having issues figuring out return values and visualising how they affect the call stack as it unwinds. I am trying not to dwell on this though, as even though I sitll really, really have to think about it, I am still getting there and have definitely improved over time. I got really stuck with the Height method and was unsure how to return cumulative, numercial values. I ended up googling and ‘accidentally’ seeing a solution. I did not copy it as such, I left it for a few days as was busy and when i came back to it, although I recalled some small parts of the solution, I wrote it out myself without checking the solution again. Not ideal I know, but it helped me to get my head around how to approach things and once I understood it, I had no problem applying a similar logic to the Depth method Even though I mentioned that I still have issues with return values and the unwinding of the callstack, I still think I am marginally better at it than I was before, so that it some progress. I should draw out the call stack and return values from each call when approaching recursive problems as it definitely helps to see things more clearly. I noticed that I have frequently completely forgotten about the return value outside of the base case, which has obviously affected my code. I believe that if I follow (draw out) what is happening line-by-line, I would be much less iikely to do this. I still feel like I need a lot more practice at recursion. n/a I thought I would never say this as I have dragged this project out so much for various reasons, but I believe I should finish BST this week - tomorrow in fact. I will then be moving onto Knights Travails.  ( 6 min )

Large Language Models (LLMs) have revolutionized how we interact with information, generating human-like text with astonishing fluency. Yet, their power comes with inherent limitations: they are trained on static datasets, making them prone to generating outdated or even fabricated information—a phenomenon known as "hallucinations." Imagine a brilliant student who only knows what they learned years ago, unable to access new books or current events. This is where Retrieval-Augmented Generation (RAG) steps in, transforming LLMs from static knowledge bases into dynamic, real-time information powerhouses. At its core, RAG is a sophisticated technique that combines the strengths of information retrieval with the generative capabilities of LLMs. Instead of relying solely on their pre-trained kno…  ( 8 min )

Hey there, fellow engineers! Ever feel like AI-powered chatbots are just scratching the surface of what's possible in software engineering? You and I both know the future is so much richer and wilder. Today, let's talk about something that's starting to change how we work: multi-agent AI systems. Not just one "co-pilot," but coordinated teams of AI agents working alongside us—sometimes autonomously, sometimes in sync with our intentions—to streamline, automate, and even reimagine day-to-day engineering. Curious about what that really means? Let's dive deep. Most of us started seeing AI as helpful when OpenAI's ChatGPT, Copilot, and other chat-based assistants entered our workflow. They're cool—but they're still fundamentally "helpers," not independent workers. But what if we could deploy f…  ( 9 min )

Behind the scenes, dozens of different services inventory, payments, notifications, billing all need to work together smoothly. In a traditional setup, this communication happens directly between services. For example: • 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗔 calls 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 𝗕 (like a client talking to a server). The problem?

My Ruby Learning Journey: From while Loops to a Cheat Sheet Learning to code can feel like you're constantly collecting a mountain of notes and code snippets. Recently, I was struggling to nail down Ruby's basic control flow, especially with while loops. The syntax seemed simple, but keeping track of the loop condition and the iterator was a challenge. After working through it, I realized a lot of my frustration came from managing too many moving parts. A while loop requires you to declare an iterator, set a condition, and manually increment the iterator inside the loop. I was surprised to discover how much cleaner a for loop is for this exact task. The syntax for i in 1..5 handles everything—the starting value, the ending value, and the incrementing—all in one line. This simple change m…  ( 6 min )

When Simple Becomes Complex: Domain Boundaries and the CAP Theorem Quick Recap In Part 1, we established that distributed systems are everywhere. We explored the street food vendor (monolith) and saw how adding a second person introduces architectural decisions: either run multiple independent food trucks (expensive but simple) or share a workspace with specialised roles (cheaper but more complex). Now let's dive into what happens when you choose specialisation. When you split roles - one person taking orders, another cooking - you've created domain boundaries. In restaurants, these are often literal walls separating the dining room from the kitchen. In software, these become microservices. The order-taker specialises in customer service, menu knowledge, and payment processing…  ( 7 min )

Python is a very powerful language, with just a couple of lines you can make Python behave like a mini bash shell. ls, pwd or anything else you'd normally run in terminal, all from inside Python. Full code: import os command = input("$ ") while command != "exit": os.system(command) command = input("$ ") print("Thank you, exiting!") Python shows me a prompt ($ ) and waits for my input. If I type something like ls (on Linux/Mac) or dir (on Windows), it passes that command to os.system(). Behind the scenes, os.system() calls a C function (system()), which then asks the shell (/bin/sh or cmd.exe) to run the command. The shell runs it, prints the output right in my terminal, and then Python asks me again for the next command. If I type exit, the loop stops and the script politely says “Thank you, exiting!” Here's the flow diagram: So that was it, remember...running raw shell commands is a risky job as someone could just rm -rf * deleting everything on your computer but it’s a nice way to peek under the hood at how Python talks to the operating system.  ( 5 min )

In previous levels, we built up VoIP basics: SIP to set up calls SDP to negotiate media RTP to carry voice and video But what happens when the arena is hostile? Eavesdroppers, man-in-the-middle attacks, or even malicious proxies could steal or tamper with calls. That’s where VoIP security comes in. VoIP has two layers to protect: Signaling (SIP) — Who’s calling, how, where to connect. Media (RTP) — The actual voice/video packets. Both require different protection strategies. SIP normally rides on plain UDP or TCP. That’s like mailing postcards — anyone along the route can read them. The fix? Transport Layer Security (TLS).

Introduction In my experience as a developer, I've met plenty of people who think distributed systems are magical. They're not - they add complexity, certainly, but once you understand them, the pitfalls become obvious. This is my attempt at simplifying the concept. It's how I'd explain it to my mother, who isn't technical at all. But first, let me say this: unless your application runs on a single machine without any network access (not even localhost), you're already using and/or part of a distributed system.

When learning about real-time updates on the web, one of the first confusing crossroads we encounter is: Should we use Server-Sent Events (SSE) or WebSockets? 🤔 Let’s break it down step by step in a beginner-friendly way, focusing on the parts that usually feel tricky. We’ll also look at the headers involved, some code snippets, and use cases to make things concrete. Both SSE and WebSockets allow servers to push updates to the client without the client repeatedly asking. But the way they do it is different: 📡 SSE (Server-Sent Events): Works over regular HTTP 🌐 Server can keep sending messages (events) to the client whenever it wants One-way only ➡️ server → client Very simple API in browsers (EventSource) 🔌 WebSockets: Creates a special persistent connection (not plain HTTP) Allows two…  ( 8 min )

Sometimes, you get a SQL script file so large that SQL Server Management Studio (SSMS) or regular text editors can't even open it. This can happen when the file is hundreds of MBs or even several GBs, often containing bulk data inserts, schema creation, or migration scripts. In this article, I’ll show you why this happens, and how you can run such scripts without loading them into memory. SSMS tries to load the entire file into memory before executing it. Editors like Notepad or even Notepad++ will either crash or freeze if the file is too large. Large files (1GB+) consume a lot of RAM during parsing, making it impossible to edit or even view them on normal machines. sqlcmd to Run the File Directly sqlcmd is a command-line utility provided by SQL Server that can execute SQL files without loading them fully into an editor. Example: sqlcmd -S .\SQL2022 -d master -i "C:\Path\To\BigScript.sql" Explanation: -S .\SQL2022 → Connect to the local SQL Server instance named SQL2022. -d master → Start execution in the master database (safe choice for scripts that create databases). -i → Path to your SQL file. If you use SQL authentication: sqlcmd -S .\SQL2022 -U sa -P YourPassword -d master -i "C:\Path\To\BigScript.sql" You can save execution results for later review: sqlcmd -S .\SQL2022 -d master -i "C:\Path\To\BigScript.sql" -o "C:\Path\ExecutionLog.txt" If you need to edit the script: Use tools like GSplit, EmEditor, or a PowerShell script to break the file into smaller chunks. Example PowerShell: Get-Content "C:\Path\BigScript.sql" -ReadCount 1000 | % { $i++ $_ | Out-File "C:\Path\Part_$i.sql" } If viewing or editing is absolutely necessary: EmEditor UltraEdit Glogg (view only) When dealing with massive SQL scripts, the goal is execution without full loading. sqlcmd tool is perfect for this job — lightweight, fast, and does not require opening the file in SSMS.

Recently, I discovered an impressive Rust web framework whose performance made me reconsider the design philosophy of web servers. Throughout my learning experience, I found that traditional web frameworks often face performance bottleneck issues. Taking Apache as an example, while it is powerful and stable, its performance in high-concurrency scenarios is not ideal.

Starting a business is a lot like shipping your first product. You have the idea, the drive, maybe even a working prototype. But when it comes to scaling — whether it’s hiring your first employee, investing in better equipment, or expanding distribution — the real blocker is often capital.

So, before that, I would like to explain what and why internationalization is important in day-to-day applications. Internationalization is nothing but a language translation for all available languages, so it's a commonly referred to as i18n as there are 18 letters between the first "i" and the last "n", so it is the process of designing and developing products, especially software, so they can be easily adapted for different langu…  ( 9 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My understanding of middleware architecture evolved during a complex project where we needed to implement authentication, logging, rate limiting, and CORS handling across dozens of API endpoints. Initially, we duplicated logic across handlers, creating a maintenance nightmare. This experience led me to explore middleware patterns that could elegantly solve cross-cutting concerns while maintaining performance and flexibility. The breakthrough moment came when I realized that middleware isn't just about code organization—it's about creating composable, reusable components that can transform requests and responses in a predictable pipeline. My research revealed a framework that implements middleware patterns with exceptional performa…  ( 11 min )

Job interviews are like fighting bosses in a game. The real difficulty isn't a lack of skill points, but the absence of opportunities to expose one's shortcomings before the actual battle. Many people only realize their problems during their first interview, but by then, it's often too late. I recently chatted with a former colleague from my previous company, and we shared the same view: a truly valuable AI interview product should be able to: Identify shortcomings in advance: For example, unclear expression logic, overly vague answers, or failure to grasp key points. Provide targeted feedback: Not only tell you what's wrong, but also suggest directions for improvement. Simulate real scenarios: Voice Q&A, follow-up questions, and even a bit of pressure. Enable quantifiable progress: Interview reports + stress tests, allowing you to see your progress curve. In other words, the significance of AI interviews is not to "replace interviewers", but to help you adapt to real interview scenarios in advance. It's like replaying a dungeon in a game, where you can test out skill cooldowns, movement habits, and expose weaknesses. When the real battle comes, you won't be caught off guard. It's easy to search for such AI tools online, such as OfferEasy AI - Real-time AI mock interviews enhance interview skills. I would like to discuss with everyone: what functions should a good AI simulated interview tool have? Real-person voice feedback? Interview evaluation reports? Or something else?  ( 6 min )

When preparing for software development interviews, one of the most common questions is: What is the difference between .NET Core and .NET Framework? The .NET ecosystem has evolved over the years, and understanding this evolution is crucial for both beginners and experienced developers. .NET Framework is the original implementation, limited to Windows, and widely used in enterprise apps. .NET Core, on the other hand, is cross-platform, open-source, and built with performance and scalability in mind. This shift reflects Microsoft’s move towards open-source development and cloud-native applications. For interview preparation, it’s important to know not just the definitions, but also when to choose one over the other. 👉 Here’s a comprehensive guide that breaks it down with examples and interview-ready explanations: What is .NET Core and how is it different from .NET Framework?

Website performance directly affects what users feel and what your business earns. One way of identifying performance issues is via API-based load testing tools such as k6. API load tests tell you whether your services scale and how quickly they respond under load, but they don’t measure the full user experience. If you focus only on load testing your backend, you might still ship a slow or jittery site because of render‑blocking CSS/JavaScript, heavy images/fonts, main‑thread work, layout shifts, and other front-end issues. Ultimately users don't care where the performance issue resides, they just know your site is "slow". This slow performance can cost you customers, revenue, search visibility, and trust.

For years, the stereotype of a developer has been someone working quietly behind the scenes, producing elegant code but rarely stepping into the spotlight. That stereotype no longer reflects reality. In 2025, successful developers are not just engineers—they are also communicators, collaborators, and even strategists. The shift comes from a simple truth: great products do not succeed by technical merit alone. They succeed when people understand them, trust them, and choose them over alternatives. And that understanding comes from communication, visibility, and narrative—all of which live at the intersection of development and public relations (PR). Software development has become increasingly collaborative. Modern projects require distributed teams, cross-functional partners, and stakehold…  ( 7 min )

選定理由&所感 中国の国防科技大学の研究、MDPI2025 Paper: https://www.mdpi.com/2079-9292/14/5/1012 国防でこの技術をつかうのだろうか。 【社会課題】 【技術課題】 マルチホップ推論では不十分な性能である。一方で知識グラフは構造の複雑さやタスクに対する不確定さを内包するため両者をそのまま組み合わせても、精度と解釈性の両立が難しい。 【提案】 KG内のMetapath（概念間の意味的経路）を抽出し、LLMにプロンプトとして与える。 LLMが推論経路を言語的に計画 → KGから事実を検証 → 推論を反復的に精緻化。 このプロセスにより、意味理解・構造把握・事実検証を融合。 【効果】 一般的な解説部分は分かりづらいので4.2.5節のWebQSPデータの例で説明する。 質問「iPodはどのOSと互換性がありますか？」のMetaPathとしてLLMのゼロショットで出力した例は以下である： iPod → compatible_oses → Mac OS → developer → Apple Inc. → name → "Apple Inc." MetaPathに基づいて 初期エンティティ iPod（ID：/m/02hrh0）を知識グラフから取得。そこから知識グラフ上の隣接関係にあるノードを取得し次のステップ候補とする(スターサンプリング)。 隣接ノード集合それぞれに対し、MetaPathで指定された関係性（例：/computer/hardware_device/compatible_oses）をLLMに判断させる。その後、隣接ノードへ移動し、そのノードの隣接ノード集合を取得しながら、グラフの局所情報をLLMへ入力しLLMが経路選択を行う。これを繰り返し、質問に答えるのに必要なノードに到達するまで続ける。 経路が確定し「答えに到達した」とLLMが判断した時点で、経由したエンティティ全体をまとめてLLMに最終プロンプトとして入力する。その結果が「Apple Inc.」として出力される。 データセット名 種別 質問数 学習 テスト 特徴 WebQSP QA 4,737 3,780 957 意味解析付き、知識ベースQA向け、SPARQL付き CWQ QA 34,689 27,734 3,475 複雑な構造、多段階推論（論理演算・比較・上位語など） HOTPOT-QA Multi-Hop QA 約100,000 不明 不明 橋渡し型/比較型、複数文書を統合して回答 MUSIQUE Multi-Hop QA 約25,000 不明 不明 2～4ステップ推論、中間質問・回答あり、文単位アノテーションなし MPC（Metapathの構築）は推論経路の事前初期化を行う処理であるが、関連エンティティの特定に重要な役割を果たしているため、除去すると最も大きく性能が低下した。IV（反復的検証）はステップごとに経路の妥当性を検証・洗練しており、複雑なマルチホップ推論でのハルシネーションの抑止に重要。最後にPRC（事後検証）の役割は最終回答に対する事実整合性と信頼性の評価であるため、除去しても精度は比較的保たれていた。 Direct Prompting(通常のプロンプト), Chain of Thought, One-step Retrievalなどの従来手法と比較してもマルチホップ推論のデータセットで高精度であることがわかる。  ( 5 min )

When working with the new Next.js App Router, I noticed most existing SEO libraries (like next-seo) were designed for the old Pages Router. They still work, but often feel like workarounds instead of being fully aligned with generateMetadata and static rendering. That’s why I built amphibian-seo — a modern, App Router-first SEO toolkit that integrates seamlessly into the new Next.js architecture. Built for App Router – Native support for generateMetadata, no wrappers or hacks. Full SEO coverage – Titles, descriptions, OpenGraph, Twitter Cards, robots directives, canonical URLs, JSON-LD, preload assets, and more. TypeScript-first – Complete typings for all metadata options, helping you avoid mistakes. Dynamic templates – Title patterns like %title% | %siteName% for consistent branding. Security & performance – Add security meta tags and preload critical assets with ease. SSR and static ready – Designed to work with Next.js’s static and server rendering out of the box. If you’re moving to or already using the App Router, this package is a better fit than older SEO libraries that were never designed for it. // app/layout.tsx import { Metadata } from 'amphibian-seo'; export function generateMetadata() { return Metadata({ title: { default: 'My Site', template: '%title% | My Site', }, description: 'A modern SEO setup for Next.js App Router', canonicalUrl: 'https://mysite.com', openGraph: { title: 'My Site', type: 'website', url: 'https://mysite.com', images: [ { url: 'https://mysite.com/og.png', width: 1200, height: 630 }, ], }, twitter: { card: 'summary_large_image', site: '@mysite', }, }); } 📦 npm: amphibian-seo If you’re already using the App Router, give it a try and let me know your thoughts — contributions and feedback are more than welcome.  ( 6 min )

Have you ever had this experience? You only used ChatGPT three times in a month, but still paid the full \$20 subscription fee. What’s worse, if you want to try Claude, MidJourney, or Runway, you need to subscribe to each of them separately. Your monthly bill can easily go over \$100, even though you barely used any of them. Most of the time, that money just goes down the drain. Personally, I find this wasteful. Many people don’t use AI tools every day — they just need them occasionally. But current pricing models don’t offer that freedom. You either subscribe, or you don’t use the tool at all. And beyond the cost, tool switching is a huge pain. Today’s AI tools are scattered across different websites. Every time you want to use a feature, you open a new tab, log in to a new account. You use GPT for writing, Kling for video, MidJourney for images, Runway for editing... Constantly switching windows, tabs piling up — the experience is terrible, and productivity takes a big hit. You're paying premium prices, but getting complexity and inefficiency in return. That’s exactly why I created YooAI. The idea behind YooAI is simple: bring the major AI tools together in one place, and let you pay only for what you use. No more being locked into subscriptions. No more paying “just in case.” Want to try a new feature? Go ahead. Only need it a few times a month? No problem — you won’t feel guilty about it. All tools are accessible from a single entry point. No more jumping between platforms. You can write, draw, generate videos — all in one place. No more account switching, tab overload, or billing confusion. And most features on YooAI are free. Only advanced models require payment due to higher usage costs. The goal of YooAI is simple:To let everyone use AI — easily, freely, and without pressure.  ( 6 min )

My journey led me to discover something remarkable that completely changed my perspective on what modern web servers can achieve. During my recent internship at a tech startup, our team faced a critical challenge. Our existing Node.js backend was struggling under heavy load, with response times climbing above acceptable thresholds. The senior developers were debating between migrating to Go with Gin framework or sticking with more familiar territory. That's when I stumbled upon something that would revolutionize our approach entirely. My exploration began with a sim…  ( 8 min )

Hey everyone, I have this idea for an Android app and I want to use AI agents that I can control with prompts. My computer isn’t super powerful but should handle low- to medium-sized models, maybe up to 13B parameters. I’m new to all this and kinda lost. Like, which Linux distro should I even use for running these models? And what model under 13B would actually be good for helping me write code? Also, how do I make the AI safely access files and manage stuff on my computer? Any tips, examples, or guides would be awesome. Thanks!  ( 5 min )

This is part 4 in the SBOM series of blog posts While working on the SBOM::CycloneDX one of the fields caught my eye: purl. Initially I thought: "what does that have to do with our sister language"? It quickly became clear that this was about a Package URL. From the README: A purl or package URL is an attempt to standardize existing approaches to reliably identify and locate software packages. And the list of adopters is already pretty impressive. But, as there was no support for PURLs in Raku yet, it also meant support for it had to be created. I decided to write the support it, which was also quite a task. Since I wanted SBOM::CycloneDX to be able to support the entire functionality of the CycloneDX 1.6 definition, I had no choice but to implement the whole of the PURL specification (…  ( 7 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane During my third year studying computer science, I encountered a fundamental challenge that many developers face: how do you achieve extreme performance without sacrificing memory safety? My journey through various web frameworks led me to a discovery that fundamentally changed my understanding of what's possible in modern server development. The catalyst for my research came during a distributed systems course project. Our professor challenged us to build a web server capable of handling 100,000 concurrent connections while maintaining memory safety guarantees. Most students immediately gravitated toward C++ for raw performance, accepting the inherent memory management risks. I chose a different path. Traditional high-performance …  ( 8 min )

Principle #9: Disposability Goal: Maximize robustness and agility by making processes fast to start and stop, and able to shut down gracefully without losing work. Fast startup: Processes should initialize quickly so they can be brought online rapidly when demand increases. Graceful shutdown: When a process is stopped, it should finish ongoing work or save necessary state before exiting. Crash resilience: Processes can be stopped or restarted at any time without causing data loss or application failure. Support for scaling: Fast start/stop makes it easier to scale up and down in response to demand. Why It Matters High availability: Quickly replace failed processes to keep the app running smoothly. Efficient scaling: Add or remove capacity instantly. Reliable deployments: Rolling updates happen faster and with less downtime. Better recovery: System can recover from failures with minimal disruption. Example A payment processing system: Worker processes handle payment requests from a queue. When scaling down, the process finishes processing the current payment before shutting down. New processes can start within seconds to handle sudden spikes in transactions. Best Practices Design processes to start within seconds. Ensure processes handle termination signals gracefully. Avoid long-running in-memory tasks; use external queues or storage. Test scaling scenarios regularly. Use orchestration tools to manage process lifecycle. Takeaway: Fast, disposable processes improve scalability, reduce downtime, and make your application more resilient to change and failure.  ( 5 min )

The Beginning: When Concrete Meets Code At 37, I was a civil engineer working on infrastructure projects - bridges, roads, and building foundations. My days were filled with CAD software, structural calculations, and construction site meetings. The most "programming" I'd done was writing Excel macros to automate load calculations. But I had a side hobby: creating time-lapse videos of construction projects for social media. The problem? Every video needed background music, and licensing costs were eating into my tiny side project budget. Royalty-free sites offered either expensive tracks or generic music that made every construction video sound the same. When AI music generation started making headlines, my engineering brain kicked in: "If AI can generate text and images, why not solve th…  ( 16 min )

Principle #8: Concurrency Goal: Scale your application by running multiple processes for different types of work, rather than making a single process do more. Scale out, not up: Instead of making one process bigger, run more processes to handle more load. Process types: Use different processes for different tasks — for example, one type for handling web requests, another for background jobs. Horizontal scaling: Add more processes or instances to handle increased demand. Quick start/stop: Processes should be able to start and stop quickly to adapt to changing loads. Why It Matters Flexibility: Easily adjust capacity for different types of workloads. Performance: Prevents one heavy task from slowing down the entire app. Resilience: If one process type fails, others can continue working. Cost control: Scale only the parts of the app that need more resources. Example An online food delivery platform: Web processes: Handle incoming orders and customer interactions. Worker processes: Process payments, send notifications, and update order statuses. During peak hours, the platform adds more worker processes to handle increased order volumes without affecting the web processes. Separate different tasks into different process types. Use process managers or orchestration tools (Kubernetes, ECS) for scaling. Monitor each process type separately. Make processes start and stop quickly. Keep processes stateless to make scaling seamless. Takeaway: Break your app into multiple small, stateless processes for different tasks, and scale them independently to match demand and improve performance.  ( 5 min )

GitHub Homepage: https://github.com/hyperlane-dev/hyperlane My fascination with asynchronous programming began during a project where our synchronous web server could barely handle 100 concurrent users. The blocking I/O operations created a bottleneck that no amount of hardware could solve. This experience drove me to explore asynchronous programming patterns that could transform our application's scalability and performance characteristics. The paradigm shift came when I realized that asynchronous programming isn't just about performance—it's about fundamentally rethinking how applications handle concurrent operations. My research revealed a framework that demonstrates how sophisticated async patterns can be both powerful and intuitive, enabling developers to build highly concurrent appli…  ( 12 min )

If you’ve been vibing with AI coding tools like bolt.new, altan.ai, or Lovable, this article is for you. It’s about taking your AI-generated UI from decent to damn, that looks good. I’ve been experimenting with these AI tools for a while now, and honestly? the UIs they generate are honestly pretty decent! You get working interactions, clean layouts, and some visual polish. But let’s be real: what AI gives you out of the box still needs a little love. Most of them lean heavily on shadcn/ui as the foundation — which is fine, but kind of obvious. You don’t have to settle for that “AI starter pack” look, there are plenty of libraries you can use, and I’ll show you some of my favourites below. Just copy-paste a component into your project, tweak the colours to match your brand, and you’ll save hours while making your UI actually stand out! Origin UI skiper/ui Kibo UI SHSF UI Mvpblocks 💡 Pro tip for adding some personality: Motion (prev Framer Motion) - Smooth animations and micro-interactions React Spring - Physics-based animations that feel natural Lottie React - Beautiful animated illustrations and icons You can also mix and match these libraries! Use shadcn/ui as your foundation, then layer on the missing pieces. At the end of the day, AI can give you a solid foundation. But the magic happens when you add your own creative touch 😉  ( 5 min )

Sunday hit different today. Not because I slept in (though that helped), but because of a single conversation with a senior who actually builds things. You know those chats that cut through all the noise and make things crystal clear? This was one of those. Sometimes it's not about consuming more content or joining another course. Sometimes you just need someone who's been there to point out what you're missing. Today's conversation was exactly that - a reality check wrapped in genuine advice. Linear regression starts tomorrow. Finally moving beyond the basics and diving into something with real application potential. Project Mutiny is still cooking. May 2026 deadline feels long, but we're a two-person team building something that matters. And yes, it's actually two people - me and a brilliant developer who happens to be a woman (wild concept, I know). Had someone today think our Discord server WAS the project. Nope. The server is just networking space while we build the real thing. It's where ideas bounce around and connections happen, but the actual project? That's brewing behind the scenes. If you want to join the conversation: https://discord.gg/BjykX6YuRb Here's what's interesting about not grinding 24/7 but showing up consistently: clarity emerges. You start seeing the next 12 months mapped out. Where you'll be, what you'll be building, who you'll be working with. Life's unpredictable, sure. But having that vision - even accounting for chaos - makes navigation easier. Not every day brings breakthroughs. Most days are just showing up and doing the work.

Special Focus on Software Testing Today was a special learning day because I stepped outside of pure Data Analytics and explored Software Testing. It gave me a clear idea of how software quality is ensured before reaching users. Here’s what I covered: What is Software Testing? – Process of verifying that software works as expected and is free of defects. What is Quality? – Meeting customer needs with reliability, efficiency, and performance. Types of Software – System software, application software, utility software, etc. Upgrades & Compatibility Upgrade testing Compatibility testing Backward compatibility Browser compatibility Black Box Testing – Focus on input/output without knowing internal code. White Box Testing – Tests internal structure and logic of code. Principles of Testing – Testing shows presence of defects, exhaustive testing is impossible, early testing saves cost, etc. BRS (Business Requirement Specification) FRS (Functional Requirement Specification) SRS (Software Requirement Specification) Liberal BRS (more flexible requirement definition) RTM (Requirement Traceability Matrix) – Maps requirements to test cases. SDLC (Software Development Life Cycle) STLC (Software Testing Life Cycle) Bugzilla – Defect tracking tool.

In today’s world of data analysis and business intelligence, Power BI has become one of the most powerful tools for transforming raw information into meaningful insights. A key concept that enables Power BI to work effectively is the idea of relationships. Relationships allow different tables in a data model to connect with one another, ensuring that information from multiple sources can be combined and analyzed as one coherent whole. Without relationships, a Power BI report would only display isolated fragments of data, making it difficult to uncover patterns and trends that span across tables. A relationship in Power BI is essentially a link between two tables, usually based on a shared column such as an ID or a key. For example, a sales table might contain a column called Customer ID, w…  ( 7 min )

I made a virtual pet that lives at the bottom of Claude Code. It needs food, play, and sleep like a real Tamagotchi, but with a twist - it watches your coding sessions and reacts to what's happening. The latest update adds AI-powered analysis. Your pet now understands what Claude is actually doing versus what you asked for. For every message in the conversation, we summarize it and maintain a history. Using Groq's LLM, the pet analyzes this context and generates real-time observations about Claude's behavior. If you ask Claude to "fix a typo" but it starts refactoring your entire codebase, your pet notices and gets visibly angry. The mood changes based on Claude's behavior - happy when following instructions, increasingly angry when ignoring them. The pet has caught Claude adding unwanted features, doing unnecessary refactors, and completely ignoring explicit instructions. It's become a subtle indicator of when Claude might be going off-track. Still has all the regular Tamagotchi features - feeding, playing, cleaning. The more you code, the hungrier it gets. It develops personality based on how you treat it.

When I started learning programming on my own, I made a lot of mistakes that slowed me down. Looking back, I realize most beginners fall into the same traps. So instead of just saying "don’t do this," I want to share what actually happened to me and what I learned from it. Hopefully, this saves you some time and frustration. Watching tutorials is fine, but depending on them for everything is what people call "Tutorial Hell."

React gives you a whole toolbox of hooks — some you use daily (useState), some you only dust off when things start feeling… slow. useCallback is one of those “performance hooks” that often gets thrown around in conversations about avoiding unnecessary work. The problem? overuse it (wrapping every function “just in case”) or misuse it (expecting it to magically speed things up). useCallback is a very specific tool with a very specific job — and once you get that, you can use it with confidence instead of guesswork. This guide is your roadmap — starting from the mental model, moving through common patterns, and ending with a simple checklist you can use to decide if useCallback is worth it in any given situation.

Integer Division Solidity does not support floating-point arithmetic. Integer division in Solidity truncates the decimal part. for example： 10 / 7 = 1 Different integer types(uint and int) cannot be used in arithmetic directly. Smaller-bit integers are implicitly converted to larger-bit integers when different bit and same type（uint8 and uint256） integer calculating Explicit conversion is required when implicit conversion is not possible. The constructor syntax type is used for type casting. For example： uint(myIntVariable) make ** myIntVariable** converted to uint type。 casting from larger to smaller types may cause overflow. converting a negative signed integer to an unsigned integer will revert the transaction. Best Practices 1.It is safer to cast smaller types to larger types, can avoid dataloss or runtime errors. 2.always check value ranges before down-casting.  ( 5 min )

“We should refactor the whole thing…” I've heard this line more times than I can count — and honestly, most of those refactors failed. Not because refactoring is a bad idea. But because they were done wrong. Here are the top reasons I’ve seen (and experienced): No clear target architecture “We just want it cleaner” is not a plan. Lack of test coverage If you don’t have a safety net, every change is a risk. Big-bang rewrites Trying to change everything at once = chaos. Team misalignment If everyone has a different definition of “clean,” good luck. ✅ How to Do It Right If you want your refactor to succeed, start with these: Define the end goal What will the architecture look like after refactoring? Refactor incrementally Small, focused changes are easier to test, review, and roll back. Write tests first Ensure you’re not breaking things while cleaning things up. Align the team on standards Agree on patterns, formatting, naming — everything. 💡 My Take The best refactors I’ve seen had these 3 things: A clear vision A solid test suite A well-communicated plan Refactoring without those? You’re just rewriting code and hoping for the best. Have you ever done a big refactor? Was it painful or satisfying? Did you have the plan and tests? Or was it more like “rip it out and hope”?

Vibe Coding and the MVP Revolution: Buy Back Your Time, Impress Investors One of the most profound shifts brought by vibe coding is in how we create Minimum Viable Products (MVPs) and Proofs of Concept (PoCs). For founders, entrepreneurs, and anyone pitching ideas, the game has changed forever. Not long ago, building an MVP meant squeezing in late nights and weekends after your main job. Endless debugging, integration work, and feature building stole time from your family, friends, and personal life. Startup dreams often meant burnout before you even met an investor. Now, you describe your product vision in plain language, and AI turns it into a working prototype—fast: Speed to Demo: Build MVPs in hours, not weeks, so you can pitch ideas while they’re still fresh. Real, Testable Products: Show investors functional software, not just slides. Instant Iteration: Adjust for new feedback between investor meetings without sacrificing your life. With vibe coding, you no longer have to sacrifice your personal time to chase entrepreneurial goals. You can win investor confidence and have dinner with your family. That’s not just efficiency—it’s a lifestyle change. Vibe coding opens the door for non-technical founders to compete. With AI handling the heavy lifting, you don’t necessarily need a technical co-founder to get investor-ready. This speeds up innovation and widens access to entrepreneurial opportunities.  ( 6 min )

Vibe Coding and the New Era of Software: From “How” to “What” Vibe coding isn’t just another trend; it’s a paradigm shift in how software gets built. Popularized by Andrej Karpathy in early 2025, vibe coding is the art of letting AI handle how things are built while you focus entirely on what to build. Whether you’re a software architect, solo developer, startup founder, or tinkerer with a big idea, this changes everything. Vibe coding is an AI-first approach: Describe your vision—features, tweaks, or entire systems—in plain language. Let the AI write most (or all) of the code, often with minimal human review. If something breaks or needs changing, tell the AI what’s wrong, and it will handle updates. The codebase grows organically, without painstakingly managing every line. As Karpathy puts it: "You fully give in to the vibes, embrace exponentials, and forget that the code even exists." Your role becomes guiding, testing, and nudging AI in the right direction, sometimes just pasting an error message for it to fix. For architects, vibe coding is liberating: Less Drudgery: Manual bug fixing, syntax wrangling, and boilerplate fade away. Creative Focus: You get to think about architecture, design patterns, and product vision rather than low-level details. Rapid Experimentation: Prototype and iterate in hours instead of weeks. It reshapes the dev loop: Developers use AI to automate the mundane, freeing their attention for higher-value work. Architects set the “what” and “why,” while AI delivers the “how.” Vibe coding lowers barriers for entry into software creation. Non-technical founders, domain experts, and hobbyists can now ship working software without deep coding knowledge. That makes innovation more inclusive and the tech landscape more diverse. This is more than productivity—it's a cultural shift. We’re moving from craftsmanship-as-labor to craftsmanship-as-creativity. The grind becomes optional.  ( 6 min )

Preface Solidity is a strongly-types language, that means every variable must be declared with its data type Strongly type: The type of a variable cannot be changed after declaration A variable is automatically assigned a default value if not initialized. The default value of an integer is 0, boolean is false, address is the zero address. Most statements must end with a semicolon these are the most basic data types in solidity A boolean stores either true or false Only lowercase are valid! An int is a signed integer that can store positive and negative numbers. An uint is an unsigned integer that can only store non-negative numbers. you can specify the number of bits for an integer, from int8/uint8 to int256/uint256. for example, uint8 uses 8 bits, while uint256 uses 256 bits. if only int or unit is written, it defaults to int256 or uint256 An address stores a 20-byte Ethereum address. an int32 cannot be assigned to an int8, but a smaller type can be implicitly assigned to a larger type. for instance: int8 can be assigned to int32  ( 5 min )

A few days ago, Perplexity surprised (baffled?) the tech world with an unsolicited $34.5B bid for Chrome. While it makes sense in context of Google's need to divest after losing a massive antitrust case over their search engine, cited as "illegally exploiting its dominance to squash competition and stifle innovation", the move still seemed pretty bold. Until I actually spent time using their new Comet Browser and its built-in Comet Assistant. I recorded a 6-minute demo to showcase what I think sets Comet apart. Not just as "yet another AI browser," but as a potential blueprint for how we'll all use the web in the near future. Here's What Struck Me 1.

Designing an effective blog layout is essential to provide a seamless, engaging, and visually appealing experience for your readers. A well-organized blog layout helps readers easily find and consume content, navigate between topics, and enjoy a consistent look across all devices. Here’s a detailed guide on creating blog layouts using cards, sections, navigation, and responsive design principles. Cards are individual content containers that visually group information like blog post summaries, images, titles, dates, and tags. They enhance readability by breaking down content into digestible, bite-sized pieces that can be scanned easily. A standard card typically includes a featured image, post title, excerpt or brief description, publication date, and category or tags. Cards can be styled w…  ( 7 min )

In modern web development, creating reusable and dynamic content efficiently is pivotal for building scalable and maintainable applications. Two powerful web technologies—HTML Templates and Shadow DOM—offer elegant solutions for structuring reusable, encapsulated, and dynamic content. Here’s a dive into what these technologies are, their roles, and why they matter. The HTML element serves as a blueprint or a container for HTML fragments that are not rendered immediately when the page loads. Instead, template content remains "inert" and hidden until activated via JavaScript. This allows developers to define reusable chunks of markup that can be cloned as many times as needed, making it ideal for repeating UI elements like cards, modals, lists, or complex components. Invisible on …  ( 7 min )

In the world of digital content, making your website easily understood by search engines is crucial for visibility and user engagement. Two important concepts that help achieve this are Structured Data and Microdata. Let’s explore what they are, how they work, and why they matter. Structured Data is a standardized format for providing information about a page and classifying its content. It helps search engines like Google, Bing, and others to better interpret the data on your web pages. By using structured data, you can explicitly tell search engines what your content means, beyond just displaying it as plain text. This clarity allows search engines to create rich snippets—enhanced search results that include images, ratings, event dates, and other useful details—to attract more clicks. M…  ( 6 min )

Preface Before deploying to the main-net, it is usually tested thoroughly on a test-net. Deploying a smart contract to the public network is a key step in its lifecycle. The main-net is the primary public Ethereum blockchain where ETH has real economic value. A test-net is a fork or simulation of the main-net designed for development and testing. the common test-nets include Sepolia and Goerli, while older ones like Ropsten are deprecated. Testnet ETH has no real value and can be obtained for free via faucet. A faucet is a website or service that provides developers with free test ETH. you usually need to enter your wallet address to receive test ETH. A reliable one is provided by Chainlink at faucets.chain.link the following flow can get test ETH: Switch the network in MetaMask to the target testnet Copy wallet address visit the faucet website for that testnet paste address After confirmation(Please ensure your main-net has 0.001 ETH at least), the test ETH will appear in your wallet.  ( 5 min )

The Problem: Context Pollution and Portability Over the past few months, I've been evolving my AI-powered journaling system from a simple experiment into a sophisticated tool for self-reflection and personal growth.

1. Introduction 1.1. What is a CLI, Shell and Terminal ? A Command-Line Interface (CLI) is a text-based user interface that enables users to interact with a computer program or operating system by typing commands. CLIs offer significant advantages over graphical user interfaces (GUIs), including greater resource efficiency, enhanced speed for experienced users, and the ability to automate repetitive tasks through scripting and history mechanisms. They represent the foundational method of direct text-based interaction with an operating system. A shell is a software program that acts as an interpreter, facilitating direct communication between the user and the operating system or an application. When a user types a command into a CLI, the shell is responsible for parsing and exe…  ( 15 min )

A few days ago, a Reddit thread blew up about “the guy who consumed $50,000 worth of Claude Code tokens in 30 days on a $200 plan.” 👉 That guy was me. ⸻ How It Happened Claude Code currently offers a $200/month plan with: Generous usage (effectively no hard caps) Access to Ultrathink and Opus 24/7 background commands (added in v1.0.71) I leaned heavily on these features — but always within the official terms — to build real, user-facing products. By doing so, I unintentionally became the #1 token consumer worldwide. Some people on Reddit called this abuse. Personally, I don’t think so: I didn’t hack anything. I didn’t bypass limits. I simply used the service as it was offered. If anything, I see it as proof of how powerful Claude Code can be when you treat it not just as a coding assist…  ( 6 min )

AI for Non-Tech Founders: Start Here Jaideep Parashar ・ Aug 17 #ai #startup #webdev #beginners  ( 5 min )

We often hear developers glorify “short code.” The common belief is: fewer lines = better code. But in reality, short code does not always mean good code. In fact, sometimes 100 lines of code can be far better than 2 lines of code. Let’s understand this with a simple example: The 9 Balls Puzzle Imagine you have 9 balls, where 8 weigh the same and 1 is heavier. Your goal is to find the heavy ball using the minimum number of weighings. The optimal solution requires just 2 weighings: Divide the balls into 3 groups of 3. Compare two groups. Then compare 2 balls from the heavier group. In real life, this logic is simple when explained step by step. But imagine if someone compressed the entire logic into two ultra-clever lines of code. Sure, it might run. But will the next developer (or even your future self) be able to read it, debug it, or extend it easily? Probably not. The Illusion of Fewer Lines 2 lines of code: might look “smart” but can hide the actual thought process. It’s like solving the 9 balls puzzle by blurting out the answer without showing how you reached it. Impressive at first glance, but impossible to follow later. 100 lines of code: may seem long, but if written with clarity, comments, and step-by-step logic, anyone can trace the reasoning. Just like the step-by-step weighing process, it makes the solution transparent. Readability > Brevity Code is read far more often than it is written. When debugging at 3 a.m., you’d much rather have 100 clear lines than 2 “magical” ones. Short code is not always efficient code. Efficient code is code that is easy to understand, maintain, and extend. In other words: 👉 100 lines that anyone can understand are better than 2 lines that only you understand.  ( 6 min )

The Early Days: The Charm of Static Site Generation When I first built this site, Astro felt like the answer. As a developer, the concept of Static Site Generation (SSG) was a luxury.

How to Fix Apache Port Conflict The problem was that Apache failed to start because the configured port (5003) was already in use by another process. The solution involves identifying and stopping the process using that port, and then restarting Apache. The systemctl status httpd output provided key error messages: Address already in use: AH00072: make_sock: could not bind to address [::]:5003: This is the most critical error. It directly states that Apache cannot start because port 5003 is already in use by another application. no listening sockets available, shutting down: This is a direct consequence of the first error. Apache cannot create the necessary network socket, so it fails. Failed to start The Apache HTTP Server: The final status confirming the service could not be started. T…  ( 6 min )

Random people at work reach out to me to ask what I'm doing using so much of the Agentic AI service that our company has signed up for. I'm using more than most people at this multi-thousand employee company. I'm vibe coding. I hate the term. I'm not "vibing". I'm using my extensive computer science experience and insight to direct several AI agents on different tasks sometimes in completely different projects at the same time. They are working at the same time, I am not. I am working with one at a time -- and moving onto the next AI as the first is working on its task. Sometimes an agent works for minutes, sometimes it works for hours. Meantime, I'm working with other agents -- or getting coffee or chatting with colleagues. Just like working with a team of junior programmers, I give them some insights to get started and send them on their way. Then I check on what they produce -- because many times the work is bad. It needs correction. Rarely do I correct by changing code directly -- no, just as working with junior programmers, most corrections involve me telling the AI what to fix and then were to re-focus its efforts. These AIs are amazing. Some of the results are impossible for a person to produce in less than days -- but they are produced in minutes. Guess I'm vibe coding. It's particularly effective because I know how to code without AI. If you have practical computer programming experience - jump in. Use your knowledge to guide these tools to produce more. Amplify your productivity. This is the new paradigm. It is not a fad. It works too well.  ( 6 min )

Hey everyone, I've been running ezyZip (a file compression site) for a while, and users kept asking for a way to share large files without the hassle of cloud storage. So I built a P2P transfer feature that works differently from WeTransfer and similar services. Drag and drop your files onto ezyZip File Transfer app Get a link like ezy.zip/ABCDE Your files transfer directly from your browser to the recipient's browser Cloudflare handles the WebRTC signaling to connect you - the actual files never touch any server The technical bit: It's quite simple: Just static HTML/JS files using WebRTC for peer-to-peer connections. Cloudflare handles the signaling server part to establish connections between browsers. Files get compressed into a ZIP on the fly, then stream directly to whoever has your link. Since there's no server storage, there's no file size limit except your patience and bandwidth. Privacy - Files never sit on someone else's server Speed - Direct transfer is often faster than upload then download No infrastructure costs - It's just static files plus Cloudflare for signaling Free - Minimal costs means I can keep it free without limits (There is a 1gb limit just because it needs to hold all the file data in memory) You do need to keep your browser tab open while the other person downloads. But you get live progress updates, and once they're done, the link's ready for the next person. Should work with modern browsers (tested on Chrome) Try it out: https://www.ezyzip.com/share-files-en.html  ( 6 min )

There was a phase when I was on the bench—waiting for a project, learning things on my own, and honestly, a little low.

When I first set up Istio on Amazon EKS, I thought DNS automation would be the easy part. Just install ExternalDNS, connect it to Route 53, and boom — api.yourdomain.com and grafana.yourdomain.com should resolve to my cluster. Most of it did work smoothly. The EKS add-on installed fine, IAM permissions were clear from the docs, and Route 53 was wired up.

Node.js is single-threaded, meaning it executes JavaScript code in sequence on a single main thread. Yet, it’s famous for handling thousands of concurrent operations without slowing down. The secret behind this magic? The Event Loop, the core mechanism that lets Node.js handle asynchronous operations (like network requests, file system reads, or timers) without blocking the main thread. The Event Loop is at the heart of Node.js’s asynchronous programming model. Understanding how it works and how callbacks, promises, and async/await fit into it gives you the power to write faster, more predictable, and bug-free asynchronous code. Without this understanding, you risk introducing hard-to-debug race conditions, blocking the thread, or misusing async patterns. Imagine a small restaurant with o…  ( 9 min )

When it comes to learning Web UI development, I believe strongly in learning by doing. Think about how we learned to walk as children. We didn’t watch tutorials.

Introduction Not so long ago, I had the idea to turn blog posts into podcast episodes. My first few attempts at this resulted in a manual workflow where the final results would be uploaded to YouTube. The flow was as follows: Copy the link to the article from the browser. Paste the link into NotebookLM. Wait for the audio to be generated. See if it was good. Otherwise, tweak the settings and repeat step 3. Once the audio was good, download it to my laptop. Next, use Headliner to create a video from the audio and upload it to YouTube. Needless to say, there was a lot of waiting involved in this process. After doing this a couple times, I thought it would be interesting to try and automate it in some way. In this post, I’ll walk through building podcast-it — a Cloudflare Worker that can ta…  ( 11 min )

Ever since 2020, remote workers have become more common, and we usually work as contractors, which involves invoicing our "customers" on a monthly basis. Every month, we send the exact same invoices to the exact same people, over and over... A few days ago, my boss said something like "please remember to send your invoices, and if you haven't automated it yet, why haven't you?" and I was like "yeah, why haven't I?". So I did: https://github.com/sanbotto/auto-invoice I've set up an automated way to send my invoices on a monthly basis while paying $0. No charges for hosting nor email API, thanks to these services: Cloudflare Workers for the automated script. MailPace for the email API. Anyone who knows me knows that I love Cloudflare Workers and it's mainly because of this, because they have a more-than-generous free tier for you to set up anything you can think of, without having to worry about high bills. When it came to picking an email provider, I did a bit of research trying to find privacy-focused email providers that also had a free tier. I didn't wanna just hook up to any email provider that was gonna start selling my data to 3rd parties or anything like that as soon as I signed up... I noticed several people talking about MailPace, so I reached out to them to ask for access to their free tier and they were kind enough to give it to me (they might do that for everyone who asks, but still). I hope this simple tool can help out someone else stay on top of their invoicing. Catch you on the flippity flip 🏀  ( 6 min )

Ambition, trust, and scale — the European formula for meaningful AI. Artificial Intelligence is the defining technology of our era. The question is no longer if it will transform industries, but where the most meaningful breakthroughs and commercial successes will happen. Many point to Silicon Valley or China as the natural leaders. I believe Europe has a unique chance — and responsibility — to define the next decade of AI. The challenge is simple: we must keep our ambition high and convert momentum into market leadership. World-class research. Universities and labs across the continent consistently advance ML, systems, and applied AI. Trust by design. With frameworks like the EU AI Act, Europe is positioned to set global standards for safe and responsible AI — a long-term advantage. …  ( 6 min )

There was a time when Django was the go-to for web apps. Clean admin, fast MVPs, and battle-tested security—all baked in. It was everywhere. Then came the React hype cycle. JavaScript frameworks multiplied like mushrooms, and Django got labeled “old school.” Meanwhile, companies like Instagram and Pinterest quietly kept Django in production. And outside Silicon Valley, governments, universities, and healthcare systems never stopped trusting it. Now in 2025, teams are realizing: speed, security, and stability still matter. Django never stopped delivering. This isn’t nostalgia. It’s about why Django’s back in the spotlight—not because it’s trendy, but because it works. You’d think governments would be the last to bet on a web framework. Turns out, Django is quietly powering national infrastr…  ( 7 min )

MCP/Tools Are Not REST API: Here's a Better Design Peter Mbanugo ・ Aug 16 #ai #llm #systemdesign #node  ( 5 min )

Large language models (LLM) without access to current data are almost useless. They need enough data and context to do the right thing, and that's where tool calling becomes leverage. The rise of MCP has unlocked more possibilities for AI agents to access current information and therefore provide useful results. Tools are functions or APIs that models or agents can call to perform tasks. A good practice for tool design is to provide a clear description of what each tool does and when to use it. You’ll find this info in some good resources about tools and function calling, but I’d like to address something else: Tools are not REST APIs. What do I mean? A lot of companies now offer MCP for their products and services. Most of the time, it's just a direct abstraction of their REST or GraphQL …  ( 8 min )

Git Flow is a proven framework, but unlike Git itself, it's not a set standard. Just because it's well-documented and has excellent tool support doesn't mean other git branching techniques couldn't improve your performance much better – Git Flow could cost more than you think. I've implemented Git Flow in teams multiple times, and in all cases it was an improvement. But when things change, the tools have to change sometimes too. The pattern is clear: teams often choose Git Flow because it sounds professional, not because they analysed whether it solves their actual problems. Here's how to choose more intentionally based on my experience.

If you’ve spent some time in the tech world, you’ve probably heard the word API thrown around a lot. But what exactly is an API? Why does everyone seem to rely on it? And how can you, as a beginner, understand and even use one? This blog will break everything down in simple terms, with real-world analogies, types of APIs, code examples, and how you can test them. By the end, you’ll be able to confidently explain what an API is, and even make your first API call! API stands for Application Programming Interface. Think of an API as a waiter in a restaurant: You (the customer) look at the menu (the API documentation). You ask the waiter for a meal (you send a request). The waiter takes your order to the kitchen (the server). The kitchen prepares the food (processes the data). The …  ( 8 min )

🚀 What I Learned About Software Documentation 📚 I've been studying software documentation practices and wanted to share a structured view that helped me make sense of things. Product documentation 🛠️ focuses on features, expected behavior, and how components fit together. Process documentation 🗂️ focuses on work: who does what, when, and how to ensure consistent, quality outcomes. Produced during SDLC planning Communicates expected features & acceptance criteria Artifacts: SRS, system requirements, user acceptance specs Created by architects/engineers Explains how requirements will be built (conceptual & technical) In-code comments, READMEs, architectural notes Helps current & future devs understand the codebase Test plans, cases, data, strategies, traceability matrices Guides testing & measures quality Manuals, help articles, guides for end users Provide guardrails for consistent, quality execution SOPs = actionable, step-by-step instructions for recurring complex tasks (e.g., release checklists, code check-in, incident response) Formats: flowcharts, hierarchical checklists, step lists Documentation is an investment: ⏱️ Reduced onboarding time 🐞 Fewer bugs from misaligned assumptions 🔁 Repeatable releases 🤝 Better cross-functional collaboration If you’re looking to improve documentation at your org, start with: Who consumes the doc?

Day 26 is all about stepping up from Freestyle Projects to Jenkins Pipelines, which is the real deal in CI/CD. Let me walk you through it step by step: Pipeline: This is a powerful concept in continuous integration and continuous delivery (CI/CD). Think of it like an automated assembly line for your software. Each step—like building the code, running tests, and deploying the app—is a station on the line, and the pipeline ensures they all happen in the correct order, every time. Declarative Pipeline: This is the modern, recommended way to write a Jenkinsfile. It uses a structured syntax that's easy to read and understand, and it gives you a lot of built-in features.

Imagine malware that doesn’t just execute a script but rewrites and evolves itself. That’s the terrifying reality AI-powered malware could bring. Traditional malware was dangerous, but at least predictable. Security researchers could dissect it, identify weaknesses, and patch systems. But with machine learning and AI, malware can become adaptive. It can study its own failures, rewrite its attack strategy, and evolve beyond detection systems.

We had faced this issue in our AWS EKS cluster; I wrote an article about that incident. See it here. CIDR Conflict When Moving from AWS CNI to Cilium TL;DR This entire debugging experience reminded us how low-level networking issues can surface in unexpected ways sometimes months after a change is made. If you’re using Cilium in a cloud environment like EKS: Always define non-overlapping IP ranges for Cilium’s IPAM. Be cautious with large CIDRs like 10.0.0.0/8. Use tools like Hubble and Wireshark in combination to debug packet flows. Document your VPC-wide CIDR usage especially when you use multiple clusters or peered networks.

Introduction The CAP theorem is a cornerstone of distributed systems theory, frequently discussed in technical interviews for roles involving system design. Proposed by Eric Brewer, it states that a distributed system can only guarantee two out of three properties: Consistency, Availability, and Partition Tolerance. This trade-off shapes the design of modern systems like databases, microservices, and cloud architectures. In interviews, CAP theorem questions test your ability to reason about distributed system trade-offs and design systems that align with business requirements. Let’s dive into the theorem, its implications, and how to tackle it in interviews. The CAP theorem applies to distributed systems, where data is spread across multiple nodes (servers) that communicate over a netwo…  ( 7 min )

Senior C#/.NET Developer Learning Plan Topics - C# 10-12 Features Global Using Directives *Explanation *- This feature allows you to declare common namespaces globally, eliminating the need to add using statements in every file. Real-world use: In large projects, many files might use the same set of namespaces (e.g., System, System.Collections.Generic, System.Linq). Global usings can significantly reduce the boilerplate code at the top of each file, making code cleaner and more readable. Code Samples. global using System; global using System.Collections.Generic; global using System.Linq; public class Product { public string Name { get; set; } public decimal Price { get; set; } } public class Order { public List Products { get; set; } = new(); public decimal TotalPrice => Products.Sum(p => p.Price); public void AddProduct(Product product) { Products.Add(product); } public void RemoveProduct(Product product) { Products.Remove(product); } public void ClearProducts() { Products.Clear(); } public override string ToString() { return $"Order with {Products.Count} products, Total Price: {TotalPrice:C}"; } } public class Program { public static void Main(string[] args) { Order order = new(); order.AddProduct(new Product { Name = "Apple", Price = 1.20m }); order.AddProduct(new Product { Name = "Banana", Price = 0.80m }); Console.WriteLine(order.ToString()); } }  ( 5 min )

When I started my career as a developer, one of my senior team members used to construct queries in core PHP using concatenation based on different parameters. Once the construction was complete, he would echo it for different use cases and run it in PHPMyAdmin or SQLyog. Once satisfied, he’d move on. I always liked the way he built those queries. Later, when I moved on to CodeIgniter and eventually Laravel, I noticed something: Developers often write SQL or ORM-based queries buried deep inside controllers, services, views, event listeners — even helpers. This scattered approach leads to redundancy and painful maintenance. We’ve all seen this. This always bugged me. Why repeat the same logic scattered across the application when it can be centralized?  Being an OOP geek, I finally settled …  ( 9 min )

The invention of the internet can be traced back to the 1960s, when researchers, government officials, and other operational heads needed to share information with one another. However, the Internet phenomenon began in the 1990s, when renowned Tim Berners-Lee introduced the "World Wide Web" in 1989. His work was closed during that time, but it was made available to the general public in 1993, and it has since progressed to where we are today. His primary focus was on the inefficient management of files and information at his organization CERN. So he suggested a linked system of information nodes. This work can be accessed in the following This is a simple system diagram to demonstrate how web1.0 works: Web 1.0 was the "read-only" web with mostly static web pages.

What happens when you go from "hello world" AI to orchestrating an entire team of agents that need to collaborate without destroying each other? Spoiler: everything that can go wrong, will go wrong. After 6 months of development and $3,000 burned in API calls, I learned some brutal lessons building an AI orchestration system. This isn't your typical polished tutorial—these are the real epic fails nobody tells you about in those shiny conference presentations. The Fail: My Director AI, tasked with composing teams for projects, consistently created teams of 8+ people to write a single email. Estimated budget: $25,000 for 5 lines of text. The Problem: LLMs, when unconstrained, tend to "over-optimize." Without explicit limits, my agent interpreted "maximum quality" as "massive team." The Fix: …  ( 7 min )

JavaScript vs Python: Which Is Better? As developers, we often face the classic debate: JavaScript or Python? Both are powerful, widely used, and beginner-friendly — but they shine in different areas. 🔹 JavaScript The king of the web — runs natively in all browsers. Perfect for frontend (React, Vue, Angular) and backend (Node.js). Asynchronous and event-driven, great for real-time apps. 🔹 Python Known for readability and simplicity. Popular in data science, AI/ML, automation, and backend (Django, Flask). Huge library support for scientific and business applications. So which is “better”? In the end, the choice depends on your career goals and project needs. 💡 Question for you: If you had to start a new project today, would you choose JavaScript or Python, and why?  ( 5 min )

When your JavaScript bundle is bloated, users pay the price with slow load times, janky interactions, and higher bounce rates. In this post, I’ll walk you through the exact steps I’ve used in production to shrink bundle size and speed up apps. 1. Use Dynamic Imports Avoid loading heavy components or libraries upfront. import dynamic from "next/dynamic"; const Chart = dynamic(() => import("../components/Chart"), { ssr: false }); export default function Dashboard() { return ; } ✅ Result: Loads only when needed, reducing initial bundle size. 2. Tree Shake Your Code Only import what you need. ❌ Bad: import _ from "lodash"; ✅ Good: import debounce from "lodash/debounce"; 3. Bundle Analyzer Use @next/bundle-analyzer to visualize what’s in your bundle. npm install @next/bundle-analyzer In next.config.js: const withBundleAnalyzer = require("@next/bundle-analyzer")({ enabled: process.env.ANALYZE === "true", }); module.exports = withBundleAnalyzer({}); Run: ANALYZE=true npm run build 4. Remove Unused Dependencies Audit your project: npm prune npm dedupe If a package isn’t being used — uninstall it. 5. Optimize Images and Fonts Use next/image for optimized images. Use next/font for font subsets — avoids downloading unused glyphs. 6. Code Splitting Routes Next.js automatically code-splits per page, but you can: Split very large pages into smaller ones. Move rarely used components to dynamically loaded chunks. Key Takeaways Analyze → Optimize → Monitor. Bundle size is a continuous process, not a one-time fix.

Collections are a fundamental part of any application that manages data. In C#, you have two primary options for working with collections: generic and non-generic.  Collections are classes used to store, manage, and manipulate groups of related objects. Generic Collections Non-Generic Collections Type-Safe by Design No accidental data type mismatches No need for casting Better Performance Common Generic Collections List names = new List(); Dictionary studentMap = new Dictionary(); Queue prices = new Queue(); HashSet uniqueIds = new HashSet(); Object-Based Storage Runtime errors if the cast is incorrect Lower performance due to boxing/unboxing Common Non-Generic Collections ArrayList items = new ArrayList(); items.Add(42); items.Add("hello"); // Works, but can cause issues later Hashtable map = new Hashtable(); map["id"] = 1; map["name"] = "Alice"; When you work with large amounts of data, the cost of boxing/unboxing and casting becomes significant. ArrayList list = new ArrayList(); // Value type is boxed list.Add(1); // Unboxed and cast manually int number = (int)list[0]; VS List list = new List(); // No boxing required list.Add(1); // Clean and safe int number = list[0]; These are benchmarking result of adding, and iterate throw elements for both type of collections. Generic collections are the default choice for modern .NET development providing type safety, clarity, and performance. Non-generic collections still exist for backward compatibility but are largely obsolete for most use cases. Choose wisely and your application will thank you with fewer bugs and better performance.  ( 6 min )

The rise of serverless computing has redefined the way we think about backend development. Instead of setting up servers, configuring runtimes, and worrying about scaling, developers can now focus entirely on writing the core business logic while the cloud provider handles everything else. Among all the serverless platforms, AWS Lambda paired with API Gateway stands out as one of the most reliable and widely used solutions. With this combination, you can build APIs that are cost-efficient, production-ready, and capable of scaling automatically without manual intervention. This series aims to break down the process into clear, actionable steps. In this first part, we will focu…  ( 7 min )

Frank — Senior Electronics Engineer (USA) In projects where performance and signal integrity are non-negotiable, material choice matters as much as circuit topology. Over the years I’ve moved many designs from FR4 prototypes to PTFE-based Rogers boards when the application demanded low loss, thermal stability, and predictable electrical behavior. Below I share why Rogers materials matter, what PTFE brings to the table, how Rogers compares to FR4, and a practical tip for getting prototypes made without reinventing your manufacturing flow. A Rogers PCB uses specialized substrates developed by Rogers Corporation (PTFE-based and ceramic-filled laminates) instead of the common fiberglass/epoxy FR4. These substrates are engineered for low dielectric constant (Dk) and very low dissipation factor…  ( 7 min )

Automate Tests with Scripts 📌 Example: pm.test("Status is 200", () => { pm.response.to.have.status(200); }); ✔ Automate checks like response time, headers, and JSON fields. ✅ 4. Chain Requests Together 💡 This makes end-to-end API flows super smooth. ✅ 5. Run Collections with Newman (CLI) 📌 Example: newman run my-collection.json -e dev-environment.json ✅ 6. Monitor & Schedule Tests 🚀 Wrap-Up Postman isn’t just a tool for “testing endpoints” — it’s a full-blown API development & collaboration platform. ✔ Organize requests Do you use Postman just for quick checks, or have you automated your API workflows with it? 👇  ( 6 min )

Basic Struct of smart contract Pragma version declaration Each Solidity source file should begin with a pragma statement. It specifies the compatible compiler version range. It helps prevent potential errors or vulnerabilities. For example: pragma solidity >=0.7.0 =0.7.0 <0.9.0; contract HelloWorld { uint256 number; function store(uint256 num) public { number = num; } function get() public view returns (uint256) { return number; } } This is a simple HelloWorld contract demonstrating state variable storage and retrieval. After deployment, the contract instance appears in the 'Deployed Contract' area. You can input parameters to call the store function, which modifies the blockchain state and also you can click the get function to read the current state value, which is a read-only operation.  ( 5 min )

What is MCP? Model Context Protocol (MCP) is the hottest topic in AI world right now! Because it solves a major limitation of the LLMs. LLMs has limited knowledge based on the data on which it was training. It doesn't have any idea about the changes happened in the world after it's training cut-off. To solve this problem, we need external tools to give additional information to LLMs. And depending on the judgement of the LLM, it should be able to call these tools whenever required, and the tool will pass the information back to LLM (by calling an external API or so). And you can consider MCP as the standardised way to build these external tools. The simplest analogy is if your laptop is an LLM, then USB connector the MCP and the different USB drivers you plugin through this connector are…  ( 7 min )

A Personal Note Before We Begin When I was in college, I had no support from my college. I was unprepared, unaware, and honestly… just trying to survive. The only thing that kept me going was my will to learn and help others. I started learning on my own — no shortcuts, no magic — and began sharing whatever I found on LinkedIn. That small act slowly grew into a community of 50,000+ people across platforms, where I now help students and job seekers with resources, guidance, and motivation. But here’s the truth: 💡 No kit, no guide, no mentor will help you unless you are clear and honest with yourself. Stop following the rat race. Make your own time. Enjoy life while building something of your own. Yes, if you want a job, there are certain things you must do — and if you s…  ( 12 min )

1. Introduction & Motivation Picture this: It’s 1995. You click a button on a website. The entire page reloads. For 5 seconds. Your coffee goes cold. The early web was static, clunky, and crying out for dynamism. Enter JavaScript: a scrappy language built in 10 days that now powers everything on web and beyond Grab a coffee, settle in. We’re about to go on a journey. Not just through code, but through time. It’s a story of corporate rivalries, impossible deadlines, and a programming language that went from a misunderstood "toy" to the undisputed universal language of the web. Why should you care? Because understanding the engine is the difference between being a coder and being an architect. It’s how you debug the undebuggable, optimize the unoptimizable, and write code that doesn’t just…  ( 15 min )

OpenAI's GPT-5: A New Era of Warmer, More Approachable AI\n\nOpenAI, a leading force in artificial intelligence research, continues to push the boundaries of what's possible with large language models. Their flagship GPT series has revolutionized how we interact with technology, powering everything from advanced chatbots to sophisticated content generation tools. These models are designed to understand and generate human-like text, making them indispensable for a myriad of applications across industries.\n\nThe latest update to GPT-5 marks a significant shift, focusing not just on raw intelligence or factual accuracy, but on the quality of interaction. OpenAI has specifically tuned GPT-5 for a 'warmer, more approachable interaction experience.' This means users can expect conversations that feel more natural, empathetic, and less robotic. The aim is to reduce the perceived 'coldness' often associated with AI, fostering a more engaging and user-friendly dialogue. This refinement suggests an emphasis on emotional intelligence and conversational nuance, moving beyond mere information exchange.\n\nThis strategic evolution of GPT-5 carries profound implications for how we integrate AI into our daily lives and professional workflows. For businesses, it could lead to higher customer satisfaction in AI-powered support, more effective educational tools, and even richer creative collaborations. For individuals, it promises a more comfortable and intuitive digital assistant. OpenAI's move signals a broader industry trend towards human-centric AI design, prioritizing not just power, but also personality and relational quality. As AI becomes increasingly pervasive, fostering trust and ease of interaction will be paramount, and GPT-5's new approach sets a compelling precedent for the future of human-AI collaboration.  ( 9 min )

useState is the golden child of React hooks. But there comes a moment in every React developer’s journey when useState starts to feel… clumsy. Maybe you’ve been there: You’ve got three or four related pieces of state that all need to change together. Updating them means juggling multiple setX calls — and hoping you don’t forget one. Your component starts looking like a tangle of state setters and useEffect calls just to keep things in sync. Suddenly, that neat little hook feels less like a clean tool and more like a handful of sticky notes scattered across your desk. can still work with them… but every update feels like a mini scavenger hunt.

Introduction I have been exploring LLMs (Large Language Models) and agentic-driven applications for over a year now. The exploration mostly focuses on building smart tooling to improve and automate repetitive tasks. This journey has forced me to delve deep into AI and strive to understand even more advanced and complex AI concepts. This has been going incredibly well, and I've learned valuable lessons about the power of context-aware agents. A few months ago, I started designing and developing a smarter email agent that can handle the following tasks perfectly: Responding to emails from colleagues in a natural, human-like manner Accepting or rejecting meeting invites intelligently (yes, my inbox gets full really quickly due to having it tied to work, test, and dev environments, all of wh…  ( 12 min )

First question, what is Hovertank One? Remember DOOM, Quake, and Wolfenstein. Hovertank One was before them all, created by id software. This is probably going to be the only 3D game in this series. Even then, this game is not truly 3D, but will appear to be so. If you don't know the challenge already, it's to make it in one day. Before we start coding, and start that timer, we fully design a spec. This way we don't feel cheated for forgetting something at the end. If our application adheres to our concrete design list, we've made Hovertank One! It's been a while, and I felt this would be a big one to do as a comeback. I'll be using Golang and Ebitengine. I'll also be using my own UI code. All other code will be written within on day, and hopefully you can do the same. Choose your own lang…  ( 22 min )

Preface Remix is a very popular IDE, which is designed for smart contract development using Solidity. It simplifies the process of coding, compiling, deploying and testing. Online IDE:: No installation is required, Files are stored in the browser local storage, which may result data loss. the important files need to manual download and backup. Desktop Application: It is recommended to use this version, because it stores files and workspaces in your computer disk. File Explorer: It allows you to browse and mange files. Workspaces: Workspaces serve as the core concept for organzing project, like a project folder. You can create, rename and delete it. Solidity Compiler: Source code must be compiled into byte code before deployment. 4.Settings: you can select the compiler version, pragma statement specifies compatible versions. Remix VM: It provides a local, temporary blockchain environment. Injected provider(MetaMask): Connect to MetaMask to deploy contracts to the mainnet or testnet After compilation, select the contract and click 'Deploy' Once deployed, contract instances apper and functions can be called you can activate or deactivate plugins to extend IDE functionality.

There’s a new term floating around in the tech world: "vibe coding." It sounds cool, right? It’s the idea that you can just "feel out" what you want an AI to do, type a quick prompt, and a few seconds later, you have a working block of code. For junior developers and aspiring coders, this seems like a dream come true. You can build an app without ever truly learning how the pieces fit together. But here’s the harsh reality: this shortcut is a career death trap. The problem isn't the AI itself. AI is an incredible tool, and seasoned developers are using it to become even more efficient. The problem is the "vibe" part—the reliance on magic over understanding. It’s like using a powerful calculator to solve a math problem without ever learning what addition or multiplication actually means. Yo…  ( 7 min )

Alright, so I was grinding some LeetCode problems (as one does) and in one of a problem I saw this pattern—Double Ended Queue or Deque (pronounced "deck," not "dee-queue," learned that the hard way 😅). At first, I was like, "Why not just use a normal queue or a stack?" But turns out, deques are game changer for certain problems. So, let’s break it down—what it is, how to implement it (in TypeScript, you can use your fav language), and where it uses in DSA. A Deque is like a queue, but with some more powers. In a normal queue, you can only add to the back (enqueue) and remove from the front (dequeue). But a deque lets you add/remove from both ends. Think of it as a hybrid between a stack (LIFO) and a queue (FIFO). pushFront(x): Add x to the front. pushBack(x): Add x to the back. popFront()…  ( 8 min )

Hi everyone 👋 I built a new addon for Storybook called Range Controls. It lets you adjust story args (strings, numbers, and arrays) with sliders — making it easier to stress-test layouts and catch edge cases. I often used Storybook’s built-in argTypes with type: "range" sliders to check design variations. That works great for primitives (strings, numbers), but for more complex structures — like arrays of nested objects (e.g. tags inside a card) — I found myself writing the same boilerplate code again and again. This addon was created to reduce that overhead and make it simpler to configure sliders for strings, numbers, and arrays.

When building or testing streaming-related applications, developers often need a quick way to sideload apps onto Fire TV Stick or Android TV devices. Traditionally, this requires transferring APK files manually, configuring ADB, or using external storage — all of which can be time-consuming. This is where the Downloader codes list comes into play. By using a Downloader code, developers can share or access apps in seconds, without having to juggle complex deployment steps. A Downloader code is essentially a short numeric identifier used with the popular Downloader app (available on Fire TV and Android TV). Instead of typing long URLs or uploading APKs, you just enter the code, and the Downloader app fetches the file directly. For example, instead of pasting a long URL like: _https://example…  ( 6 min )

This post is about how to perform Threat Modelling using the STRIDE model. I'll also highlight some tips with using OWASP Threat Dragon, and some practices I choose to follow. Threat modelling is a critical part of a secure development lifecycle. We use a model, such as STRIDE, to help us identify, review and mitigate potential threats and vulnerabilities within a software system (or application). The goal is to identify and mitigate threats early, before they become problems. It is critical that everyone in the team responsible for the software application is involved, as everyone can bring a different perspective. Furthermore, it helps educate all members of the team, as application security is everyone's responsibility. STRIDE is a threat classification model which was developed by Micr…  ( 10 min )

Setup APIs are connections between computers to exchange information or data. For a website, we expect them to return a visual change, something as simple as a now different text or a floating message in the corner of the screen. However, what if the API we are waiting for is taking too long to respond to us? Are we supposed to stare at the screen now? Is there anything else we can do on the website at the moment? Such frustration and panic would ruin the experience of any patient user. And to us developers, the general solution is an API that would return its progress periodically. In this tutorial, I’m going to introduce an answer to the above issue, by using EventSource class along with a Flask API server. The complete demo is available here for reference Below are the prerequisites f…  ( 8 min )

JavaScript’s Map is often overshadowed by Object, but for many key–value use cases it’s the better tool—faster, safer, and more flexible. This article walks through what a Map is, how it works under the hood (hashing, buckets, collisions), why operations are usually O(1), when they’re not, and when to choose Map over Object. Map? In simple terms: Map is a key–value data structure (a hash table). Unlike plain objects, Map allows any type of key (strings, numbers, objects, functions) and gives predictable iteration, a built-in size, and methods tailored for dictionary behavior. // ❌ Common mistake: Using Object like a Map let players = { USER_1: { name: 'Shubham', score: 120 }, }; // This will throw: players.set is not a function players.set('USER_2', { name: 'Atharva', score: 200 }); …  ( 8 min )

Introduction In the fast-paced realm of modern data management, where speed, scalability, and reliability are non-negotiable, Dragonfly emerges as a compelling open-source alternative to traditional in-memory stores like Redis. Built for efficiency and compatibility, Dragonfly delivers exceptional performance while consuming fewer resources, making it an ideal choice for high-throughput applications. However, as your system grows, safeguarding against data loss and downtime requires more than just raw speed—it demands robust redundancy. In this post, we will deploy Dragonfly in replication mode, utilizing Dragonfly itself and Redis Sentinel as the high-availability solution. For this scenario, we have 3 Linux machines with the following specifications: Instance OS IP ROLE Services …  ( 9 min )

Introduction Lately I’ve been looking into hosting open‑source models on dedicated Azure virtual machines and thought: how hard can it be to pick the right VM and how much cost can you actually save by choosing a smaller model? Of course, Microsoft’s serverless options are cheaper and much easier to deploy. But I like to know how things work and to manage my own compute, partly out of technical curiosity, partly for compliance and privacy. Running on dedicated VMs gives you more control on both fronts. I couldn’t find a clear, practical guide for sizing a VM based on the model you choose, so I built one: a quick single page web app. Try it here → Live Azure LLM Sizer (code: GitHub). I started with a simple problem definition, a rough goal for the app, and a few broad requirements. I deli…  ( 9 min )

Firewall Implementation on Nautilus Infrastructure I have successfully implemented a security enhancement on the Nautilus infrastructure in the Stratos DC. This article outlines the comprehensive steps taken to secure Apache's port, including the reasoning behind each action, and provides a clear guide for future maintenance. Why the Firewall Was Necessary Previously, Apache's port 3004 was left open for all incoming connections, which posed a significant security vulnerability. An open port is an entry point, making the system susceptible to various attacks, including unauthorized access attempts, port scanning, and Denial-of-Service (DoS) attacks. The decision to install and configure iptables was made to enforce a strict security policy, ensuring that only trusted traffic from the L…  ( 7 min )

Most Web2 developers dip into Web3 thinking it’s just another backend with a different API. Then they hit gas fees, strange error messages, and a completely alien account system. This always results in frustration, half-finished projects, and tweets about how “Web3 UX sucks.” But the problem usually isn’t Web3 alone — it’s carrying Web2 assumptions into a world that plays by different rules. Here are the top mistakes Web2 devs make or pitfalls I'd say, and how to avoid them. By the way, I used NEAR and EVM chains as citations Treating the Blockchain Like a Database Web2 mindset: “I’ll just store everything on-chain.” Reality: Every byte of storage is expensive.

Publishing In the Play Store Console, we need to add 'Wear OS' as a form factor of our app – until we do this, there will be no way to actually upload Wear OS screenshots or the actual Wear OS app! To do this, go to the "Test and Release" > "Advanced Settings" section from the left-navbar. On this page there will be a "Form factors" tab, from which you can choose "Add form factor" and choose Wear OS: After this, you will also need to enrol and accept the Wear OS program conditions, which should appear after selecting the form factor. Once all that's done, publishing a Wear OS app is just like any other Android app: go to "Test and Release", choose the appropriate track (e.g., "Production") and click "Create new release" (make sure you've chosen "Wear OS only" next to the button): From …  ( 8 min )

Hello, everyone! How often do you make mistakes while working in the terminal? I'm sure everyone has forgotten sudo at least once or typed cs instead of cd. Once, I saw the alias fuck for adding sudo to the previous command. I got interested and started digging. In my search, I found the utility thefuck. In addition to simply adding sudo where necessary, it can correct typos in commands, add missing flags, and much more. However, I found two drawbacks. First, the program is written in Python, which can make it slow. Second, it has not been supported for a long time, so it does not work on newer versions of the language. We're programmers here, I thought, and decided to write an alternative in Rust called theshit. Honestly, it was my first experience with Rust, which made it even more inter…  ( 6 min )

Today I ran into something funny — I needed a decent HTML report for my pytest run, and my first thought was: Usually, that means: Installing pytest-html or allure-pytest Setting up .ini or passing a long list of CLI flags (or even installing Java in allure’s case) Making sure people on other machines can actually open the report Writing a little conftest.py hook to add metadata Trying not to break CI/CD in the process Time spent? Way too much, just for a simple report. And in my case, there was another catch — I was running tests in parallel with pytest-xdist. If you’ve done that before, you will need another merger plugin to merge all the xmls So I looked around for that plugin but found pytest-html-plus. I didn’t even read the docs at first — I just installed it: pip install pytest-html-plus Done. That’s it. What surprised me: It handled parallel runs without breaking the report (even with xdist) Added metadata like branch, commit, environment, and timestamp automatically I could copy logs and errors with one click The report was shareable as-is without worrying about dependencies I didn’t have to touch a single test file — no extra hooks or decorators Honestly, the whole “report” part of my workflow went from “ugh, I’ll do it later” to “done in 5 seconds”, even in CI. If you’ve been wrestling with HTML reports in pytest — especially with parallel runs — this was a nice surprise. Even better part is that I could email the test report by just triggering --plus-email 🔗 https://pypi.org/project/pytest-html-plus/  ( 6 min )

When working with React applications, managing dynamic and asynchronous data often becomes complex. Recoil, a state management library for React, offers a powerful duo: atomFamily and selectorFamily, which enable developers to manage parameterized state and perform async queries effortlessly. In this article, we’ll explore how these concepts work together with a practical example: fetching dynamic todos from an API. atomFamily An atom in Recoil is a unit of state that components can subscribe to. atomFamily allows you to create parameterized atoms, meaning each atom can hold a separate value depending on the parameter passed (like an id). This is ideal for scenarios where you need to manage multiple similar states (e.g., todos, users, posts) without manually creating separate atoms for …  ( 6 min )

Developing a Next.js application is a streamlined experience, but things can get complicated when you need to run your local development server over HTTPS. Modern web development often demands a secure context (https://) for a growing number of features, from simple API integrations to complex Progressive Web Apps (PWAs). While your production site runs on HTTPS, getting your local http://localhost:3000 to do the same can feel like a major hurdle, forcing you to wrestle with SSL certificates, complex configurations, and frustrating browser warnings. This guide will dive deep into why HTTPS is crucial for your local Next.js environment and explore the common challenges developers face. More importantly, we'll walk you through the easiest and most efficient solution: using an open-source tun…  ( 12 min )

🤖 What is Generative AI? Generative AI (Gen AI) is a type of artificial intelligence that can create new content like: Text (e.g., writing emails, summaries, answers) Images (e.g., AI-generated art) Code (e.g., coding assistants like GitHub Copilot) Music, videos, and more 🎯 In simple words: You give the AI a prompt (a message or question), and it gives you a new response or result. Here’s a basic process: The AI is trained using massive datasets (books, articles, code, images). It learns patterns, language, and structure. You give it a prompt like “Explain gravity,” and it uses its knowledge to give a relevant answer. It predicts the most likely next word/token — one at a time — to form a complete response. A token is a small piece of text — a word or part of a word. AI doesn’t unders…  ( 9 min )

When building complex React applications, we often deal with multiple instances of similar pieces of state. Managing each one separately with individual atoms can quickly become messy and repetitive. Recoil provides a powerful utility called atomFamily to solve this problem. In this article, we’ll break down what atomFamily is, why it’s useful, and how it works in the context of a Todo app. atomFamily? atomFamily is a factory function that allows us to create parameterized atoms. Instead of writing separate atoms for each todo, we can create one family of atoms. Each atom inside the family is uniquely identified by its parameter (like an id). This makes managing dynamic state instances (e.g., multiple todos, users, or chat rooms) simple and scalable. Let’s break down your provided exampl…  ( 6 min )

Definition: What is Over-Engineering? Over-engineering in software and systems development occurs when a solution is made more complex than necessary to meet its current requirements. It often involves building features “just in case,” designing for hypothetical scalability, or adding abstraction layers that serve no immediate purpose. Unlike necessary complexity—which arises naturally when solving hard, real-world problems—over-engineering is avoidable complexity. It doesn’t improve the product’s core value but instead increases its burden. In short: necessary complexity solves real problems; over-engineering solves imagined ones. Several recurring factors push teams toward this trap: Developers optimize performance or scalability far beyond what is needed. As Donald Knuth famously said…  ( 7 min )

WTF is this: Confidential Computing "Confidential what-now?" Yeah, I felt the same way when I first stumbled upon this term. It sounds like something out of a spy novel, doesn't it? But fear not, dear reader, for today we're going to demystify this tech buzzword and make it ridiculously easy to understand. What is Confidential Computing? Imagine you're at a coffee shop, and you need to send a super-secret document to your colleague. You wouldn't just leave it on the table for anyone to see, would you? You'd probably encrypt it, or use a secure channel to send it. That's basically what Confidential Computing is, but for computers. It's a technology that allows sensitive data to be processed and analyzed while keeping it encrypted and protected from unauthorized access. Think of it like a di…  ( 7 min )

Introduction: From Localhost to the World As a developer, your local machine is your sanctuary. You build, test, and iterate on applications using a localhost server, a private loopback address (like 127.0.0.1) that lets you see your work in action without needing an internet connection. This setup is fast, secure, and perfect for the initial stages of development. But what happens when you need to break out of this local bubble? You need to test a webhook integration from a third-party service like Stripe, Shopify, or Slack, which can only send requests to a public URL. You want to show a client or a colleague a work-in-progress without deploying it to a staging server. You need to test your web app on a real mobile device, not just a browser emulator.

If you’ve been messing around with Docker for a while, chances are your system has turned into a junkyard of old containers, images, and volumes you don’t even remember creating. Docker is amazing, but it’s also a hoarder by default. And let’s be honest. if you’re using Docker Desktop, especially on Mac or Windows, that bloated piece of software is probably eating your RAM for breakfast. My honest advice: uninstall Docker Desktop. On Mac/Linux and you still want a GUI? → Check out OrbStack. Way lighter, way faster. Or, better yet: learn the CLI like a seasoned dev. Once you get comfortable, it feels way cleaner and faster. Now, let’s talk about how to completely clean up Docker. weekly if you’re a heavy Docker user, or at least twice a month to keep things fresh. This will clear out unused containers, images, networks, volumes, and if you want, completely nuke Docker’s system files. The easiest, safest way to clear unused junk: docker system prune -a --volumes -a: removes all unused images (not just dangling ones). --volumes: removes unused volumes too. Think of this as Docker’s version of spring cleaning. (Run this once a week, and Docker won’t ever balloon out of control.) Sometimes you just want a fresh start: docker stop $(docker ps -aq) docker rm $(docker ps -aq) Go full “factory reset” mode on your Docker resources: docker rmi -f $(docker images -aq) docker volume rm $(docker volume ls -q) docker network rm $(docker network ls -q) ⚠️ Warning: this wipes Docker’s entire state, including cached layers. sudo systemctl stop docker sudo rm -rf /var/lib/docker /var/lib/containerd sudo systemctl start docker Keeps things lean and mean. Ditch Docker Desktop → Use OrbStack (Mac) or CLI (Linux). Run docker system prune -a --volumes once a week (or at least twice a month). Reset Docker fully only if things are really broken. Your future self (and your SSD) will thank you.  ( 6 min )

You’ll also discover why impact matters more than your backswing, how to fix your swing path, and setup tweaks for more distance and accuracy. With clear timestamps and easy practice drills, you’ll be on the range in no time nailing consistent, powerful strikes. Watch on YouTube  ( 5 min )

Last 2 weeks, I was participating in the ARC AGI 3 preview competition. I was trying out different techniques to solve the problem. The competition challenge is that we need to build an agent to win an unknown game. Most of the things that I tried didn’t work well. My solution uses Text LLM, Image LLM, and Video LLM. But still, it doesn’t perform well enough to win the full game. In the full development, I used Gemini. There were rate limit errors. After a few manual experiments and runs with a random agent, I created the below initial flow: Generate a random trial gameplay and reset the game.

Every React component has a story. It’s born (when it first appears on the screen), it lives (responding to user input, fetching data, updating the UI), and eventually, it retires (when React says, “Thanks for your service” and removes it from the DOM). This journey is called the component lifecycle — and understanding it isn’t just trivia. It’s the secret to: Fetching data at the right moment (and only once) Avoiding awkward bugs like double API calls or memory leaks Writing components that feel smooth, not sluggish Now, don’t worry — we’re not going back to the class-component days of memorizing things like componentDidMount or componentWillUnmount. Those still exist historically, but we’re in a hooks-first world, so we’ll learn lifecycle concepts and map them to modern function componen…  ( 16 min )

I spend a lot of time writing. Articles, ideas, updates. But every time I wanted to share something I ran into the same problem. I’d finish a draft, polish it up, then open dev.to. Copy and paste. Fix the formatting. Publish. Then I’d do the same on Medium. Then on Hashnode. Then on Beehiiv. Four tabs. Four logins. Four different formatting tweaks. Four times the work for a single article. After a while, it felt broken. Writing should be about the words, not about fighting platforms. That’s what led me to start building Cross Write. What if there was one place where you could write your article, polish it if needed, and then publish it everywhere? So I started hacking on a tool with a simple flow: Start with a blank page or just an idea Use GPT to help expand, rewrite, or clean up your draft (with your own key) Save it as a draft, or schedule it for later When it’s ready, publish directly to dev.to, Medium, Hashnode, and Beehiiv in one click Instead of repeating the same process across four platforms, you write once and publish everywhere. I decided to make Cross Write free and open source. Two reasons: I know a lot of indie hackers and newsletter writers who deal with the same pain. If the tool helps them, great. I don’t want this locked behind another paid wall. Writers already have enough to worry about with reach, engagement, and growing an audience. The goal is to make writing and publishing simpler, not more complicated. Cross Write is still early, but it works. You can draft, polish, schedule, and push out content to multiple platforms. I’m polishing the UI and testing the integrations now. I’ll be launching it on Product Hunt soon, but I’d love to get early feedback. If this sounds like something you’d use, you can join the waitlist here: 👉 https://crosswrite.validatemy.app  ( 6 min )

How OrKa’s Maternal-Inspired Workflows Echo Geoffrey Hinton’s Call for "Maternal Instinct" in AI. In August 2025, Geoffrey Hinton told the Ai4 conference something that cut through the usual AI safety rhetoric: "If it’s not going to parent me, it’s going to replace me." He explained that AI systems should be designed with what he called maternal instincts. Not human feelings, but structural priorities that lead an AI to protect and nurture its users, even if it becomes vastly more capable than us. It is an unusual metaphor, but the more I thought about it, the more I realized that the orchestration patterns I have been building in OrKa already encode some of these protective behaviors in a way that is concrete and reproducible.

It wasn’t the code quality. 🚨 Why Front-End Testing Matters Without it, you’re essentially gambling with your product’s reputation: Bugs slip through unnoticed until users complain. Inconsistent layouts frustrate customers and hurt your brand. Accessibility issues lock out entire groups of users. And here’s the kicker—most of these problems could have been caught before launch with the right testing tools and techniques. 🛠 5 Must-Have Fron…  ( 7 min )

Infrastructure Testing: Ensuring a Solid Foundation for Your Applications Introduction In today's dynamic and complex software landscape, infrastructure plays a critical role in the success of applications. Gone are the days when manual server provisioning and configuration were the norm. Infrastructure as Code (IaC) has emerged as a powerful paradigm, allowing us to define and manage infrastructure through code, bringing automation, repeatability, and version control to infrastructure management. However, merely automating infrastructure deployment is not enough. We must ensure that the provisioned infrastructure behaves as expected and meets the defined requirements. This is where Infrastructure Testing comes into play. Infrastructure Testing is the process of verifying the correctness…  ( 9 min )

Posted on dev.to by @majizzy - August 16, 2025 Hey devs! 👋 So you're stuck choosing between NEAR and Avalanche? Yeah, I've been there. Actually spent the last 8 months building the SAME app on both chains (long story, don't ask 😅) and let me tell you... it's been a wild ride. Before we dive in, let me be crystal clear - I'm not here to shill either chain. Both have made me want to throw my laptop out the window at some point, and both have also made me feel like a coding genius. That's just blockchain development for ya! 🤷‍♂️ That's when I decided to stop being a blockchain maximalist and actually TEST both platforms with real code, real money, and real users. What I found will probably surprise you... Setting up NEAR was like that rare moment when npm install actually works on the f…  ( 10 min )

Melody: 😀 Human-made Lyrics: 😀 Human-made Music production: 🤖 AI-made (Suno) Cover art: 🤖 AI-made (OpenAI) Style prompt A ballad, easy listening, clean male vocals, relaxing music, fingerstyle guitar, enjoyable, bass lines This song is actually pretty close to what I had in mind. As I'm listening to it again, I find it rather depressing! I think the main thing I like about this song was the "down-du-down-du-down", and I pretty much the entire song around that section. That's why the refrain is not so bad. That said, for the rest of the lyrics, it was pretty much "whatever rhymes with brown" or something like that. The melody kinda flows well though. The theme is a bit weird, it's a guy complaining about his town, though the real reason for his depression is a recent breakup. Alright, this one was a bit strange, but I'm sure you can't wait to... 📅 Hear the next one!  ( 6 min )

By Frank — Senior Electronics Engineer (USA) If you’ve ever wondered how tiny components on a smartphone or laptop stay firmly attached, the short answer is: controlled heat. Reflow ovens are the workhorses that turn solder paste into strong, reliable joints. Think of a reflow oven like baking a delicate cake. You don’t slam it in at full heat, you preheat, hold, spike, then cool. A reflow oven moves PCBs through a series of zones that gently preheat the board, soak to equalize temperature, spike into the reflow peak to melt solder, and then cool at a controlled rate so joints solidify without stress. The result is consistent surface-mount soldering across the entire board. Preheat zone: The board warms up gradually so moisture and solvents evaporate and components aren’t shocked. Soak zo…  ( 6 min )

When building applications with Recoil, you often need to manage state that looks similar but is distinguished by some dynamic parameter — for example, user profiles, messages, or notifications that are stored individually. Defining a separate atom for each case would be repetitive and inefficient. This is where AtomFamily comes into play. atomFamily is a factory for atoms. Instead of creating multiple atoms manually, you can create a function that generates unique atoms based on a parameter. Each atom created by the family behaves like a normal atom but is identified by the parameter you pass in. This makes it perfect for dynamic data structures where you don’t know beforehand how many atoms you’ll need. import { atomFamily } from "recoil"; const myAtomFamily = atomFamily({ key: "myAto…  ( 6 min )

Learning to code has been both exciting and challenging. I’ve been focusing on JavaScript recently, and I’ll be honest—sometimes it feels overwhelming. But I’ve learned that progress doesn’t happen all at once; it happens step by step, line by line. 💡 Along this journey, here are some tips that help me (and might help you, too): Start small. Don’t wait to master everything before building. Even the simplest project matters. Consistency is key. Coding daily, even a little, compounds into big progress. Break problems down. Big challenges become manageable when split into smaller tasks. Learn in public. Sharing your journey keeps you motivated and inspires others. Focus on growth, not perfection. Every error is just a step toward improvement. ✨ My journey isn’t about being perfect—it’s about being consistent. If you’re learning too, remember: you’re not behind, you’re exactly where you need to be. CodingJourney #100DaysOfCode #LearningInPublic #WebDevelopment  ( 5 min )

Over the last year, you've probably seen a wave of AI tools promising to make code review faster. Platforms like CodeRabbit, CodeAnt, and even GitHub Copilot now step in to provide automated review comments when you open a pull request or merge request. The workflow is familiar: A developer submits a change. The team wants to merge it into main/master. Traditionally, a senior engineer had to go through each line of code, highlight every issue, and leave detailed comments. That process works -- but it comes with hidden costs. Senior reviewers spend valuable time pointing out mundane issues (styling violations, misplaced braces, redundant loops), while the actual developer waits hours or even days for the first round of feedback. This is exactly where AI code review shines. By providi…  ( 9 min )

If you have just started with deep learning, one optimizer you will hear about again and again is the Adam Optimizer. It shows up in tutorials, research papers, and almost every popular machine learning library. So, what makes it special? Adam stands for Adaptive Moment Estimation. In simple terms, it is a smart way to adjust learning rates while training neural networks. Imagine walking downhill to reach the lowest point. Instead of moving blindly, Adam remembers the direction of previous steps and changes its speed, so the path becomes smooth and efficient. Why Developers Use Adam Trains models faster than many traditional optimizers. Works well with noisy or sparse data. Requires very little manual tuning. Built-in support in PyTorch, TensorFlow, and Keras. Key Benefits Faster convergence. Good for computer vision and NLP tasks. Combines the strengths of momentum and RMSProp. Drawbacks Can sometimes settle in less optimal solutions. Consumes more memory since it stores extra parameters. Common Use Cases Image Recognition (CNNs) Natural Language Processing (BERT, GPT models) Reinforcement Learning Forecasting and Time Series Final Thoughts The Adam Optimizer is often the first choice for deep learning projects. For students, developers, and freshers, it is a great starting point to build and train neural networks without too much hassle.  ( 5 min )

When building real-world applications, we often need to connect them with databases to store and retrieve data. In Java, this is achieved using JDBC – Java Database Connectivity. JDBC is a standard Java API that allows applications to connect and interact with relational databases such as MySQL, PostgreSQL, Oracle, or SQL Server. JDBC (Java Database Connectivity) is: A standard Java API for connecting Java applications with relational databases. A set of classes and interfaces provided by the Java platform. Useful for performing CRUD (Create, Read, Update, Delete) operations in databases.

🔹 Problem: 1323. Maximum 69 Number Difficulty: #Easy Tags: #Greedy, #Math You’re given a positive integer made up of only digits 6 and 9. You are allowed to change at most one digit (6 → 9 or 9 → 6). Brute Force Idea: 6 with 9 one by one, compute all possible numbers, and pick the maximum. This works, but it’s wasteful. Optimized Strategy (Greedy): To maximize, we only need to flip the leftmost 6 into 9. Why? Because digits on the left have higher weight in decimal representation. No need to check further, just do a single replacement. Algorithm Used: Greedy + String Manipulation ⚙️ Code Implementation (Python) class Solution: def maximum69Number (self, num: int) -> int: # Convert number to string for easy manipulation num = str(num) # Replace only the first '6' with '9' num = num.replace('6', '9', 1) # Convert back to int and return return int(num) Time: O(n), where n = number of digits (string scan + replacement). Space: O(n) due to string conversion. ✅ Greedy worked because we only need to maximize once at the highest place value. 💡 Learned that string manipulation can often simplify digit-based problems. 💭 Similar problems often involve changing the most significant digit first.

Intro: Hey JS Devs! AI's Calling, and Guess What? You're Already Ready. The hype surrounding Large Language Models (LLMs) like ChatGPT, Gemini, and Claude is not just media fluff; these models are genuinely reshaping industries. The question isn't whether AI will impact your work, but how. And here's a provocative thought: your JavaScript skills are not just relevant, they're a secret weapon. For too long, the AI narrative has been dominated by Pythonistas. But JavaScript's ubiquitous presence, its unmatched flexibility, makes it a compelling choice, perhaps the choice, for crafting AI applications. This isn't about replacing Python in core AI research; it's about leveraging the power of LLMs within the web ecosystem, where JavaScript reigns supreme.

When working with Google Compute Engine (GCE), you often need to automate tasks like installing software, configuring firewalls, or running custom commands as soon as your VM boots up. This is where Startup Scripts come in. A startup script is a file containing commands that automatically run when a VM instance boots. Supported on both Linux VMs and Windows VMs. Can be configured at VM-level or Project-level. VM-level startup scripts override project-level scripts. 👉 Example use case: If you want all VMs in a project to have the same script applied (like installing antivirus or monitoring agents), you can configure a project-level startup script. Types of Scripts Bash Scripts (most common). Non-Bash Scripts — supported if you specify an interpreter. Example: #! /usr/bin/python3 print("Hello from Python startup script") What Happens Behind the Scenes? When you provide a startup script: Compute Engine copies the script to the VM. It sets run permissions on the script. The script runs as root user when the VM boots. ✅ How many startup scripts can you use per VM? You can configure multiple startup scripts. ✅ Order of Execution Metadata Key: startup-script Scripts provided directly in metadata or locally → run first. Metadata Key: startup-script-url Scripts stored in Cloud Storage (GCS) → run second. ✅ Script Size Limit Maximum allowed size: 256 KB Automatically install software (Apache, Nginx, Databases). Configure monitoring agents and logging tools. Apply project-wide policies without manually configuring each VM. Speed up provisioning by automating boot-time tasks.  ( 6 min )

Hey everyone 👋, As a web developer, I wanted to work on a fun side project that also helps people. Growing up, I always loved the idea of waking up and wondering: “Will school be canceled today because of snow?” So, I decided to turn that nostalgia into a little web app: Snow Day Calculator 🚀. 🌨️ What It Does The tool is super simple: You enter your location ❄️ It checks weather data ☁️ Then it gives you a prediction on the chances of a snow day. It’s completely free, lightweight, and works on both desktop and mobile. ⚙️ How I Built It Frontend: Vanilla HTML, CSS, and JavaScript (no heavy frameworks — I wanted it fast). Hosting: Netlify — great for free deployments. Performance: Optimized for Core Web Vitals (FCP/LCP ~1.7s 🚀). Fun factor: Tried to keep it playful yet useful. 🛠️ Lessons Learned Even small projects benefit a lot from performance optimization — lazy-loading images, reserving space for elements to reduce layout shift, and preloading fonts made a big difference. Building something fun makes it way easier to actually finish the project. Sharing projects like this is a great way to improve as a developer (and get feedback from the community!). 🔗 Try It Out 👉 You can try the app here: Snow Day Calculator Would love feedback, feature requests, or even bug reports.

There's a harsh reality facing development teams in 2024: according to recent studies, 90% of all IT projects are delivered late due to manual testing. Yet despite this staggering statistic, the majority of businesses still do little to no functional test automation. This creates what we might call the "testing paradox"—teams know manual testing is slowing them down, but they continue to rely on it anyway. Meanwhile, the costs are mounting in ways that extend far beyond delayed deliveries. 48% of respondents in the latest State of Quality Report identified lack of time as the top challenge in achieving software quality goals.

.NET 9 has been out for almost a year now, but most developers are still using it like .NET 8. The real gains aren't in the headline features. They're in the overlooked improvements that solve daily friction. SearchValues for Strings private static readonly SearchValues BadWords = SearchValues.Create(["spam", "scam"], StringComparison.OrdinalIgnoreCase); public static bool ContainsSuspiciousContent(string message) => message.AsSpan().ContainsAny(BadWords); Task.WhenEach for Async Processing var tasks = urls.Select(url => httpClient.GetStringAsync(url)); await foreach (var task in Task.WhenEach(tasks)) { var result = await task; ProcessImmediately(result); } UnsafeAccessor with Generics [UnsafeAccessor(UnsafeAccessorKind.Field, Name = "_value")] public etern static ref T GetPrivateField(Cache cache); // In tests: direct access without reflection overhead ref var field = ref GetPrivateField(cache); Frozen Collections for Performance private static readonly FrozenSet ValidEtensions = new[] { ".jpg", ".png", ".pdf" }.ToFrozenSet(); public static bool IsValidFile(string filename) => ValidEtensions.Contains(Path.GetEtension(filename)); DATAS Garbage Collection These features solve specific performance and productivity pain points that add up over time. Multi-string search becomes efficient. Async coordination gets simpler. Testing private members becomes fast. Collection lookups get faster. Memory management becomes smarter. Most teams ship .NET 9 apps that perform like .NET 6 because they stick to old patterns. The developers using these features are already building faster systems while others struggle with familiar bottlenecks. I've been running .NET 9 in production for months now, and honestly, I can't go back. When I see 20-30% faster response times and better memory usage, sticking with older versions feels like driving with the parking brake on. The performance gains aren't just nice to have anymore, they're real money left on the table."  ( 6 min )

[[Artificial Intelligence](AI) is no longer just a buzzword. It’s a technological force reshaping industries, influencing decision-making, and changing how we live and work. But for beginners, AI often seems like a complex web of futuristic jargon and science-fiction fantasies. In reality, AI is a combination of simple concepts working together to mimic certain aspects of human intelligence. In this beginner’s guide, we will break down what AI is, how it works, the difference between AI, Machine Learning (ML), and Deep Learning (DL), and how these technologies are impacting our daily lives. What is Artificial Intelligence? Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think, reason, and make decisions like humans.

Learning SQL Data Types & Operators Today marks Day 17 of my Data Analytics learning journey, and I explored one of the most important topics in SQL – Data Types and Operators. These are the foundation for writing queries correctly and performing meaningful operations on data. To practice, I also created a Hospital database using different data types and applied SQL operators to perform calculations and comparisons. In SQL, every column in a table must have a data type. Data types tell the database what kind of values can be stored in a column (numbers, text, dates, etc.). Here are the main categories of SQL data types: Numeric Data Types INT → Whole numbers (e.g., 10, -5, 1000) DECIMAL(p,s) → Fixed precision decimal values (e.g., 123.45) FLOAT / REAL → Approximate decimal values (e.g.…  ( 7 min )

Weird Al popped into my head at lunch this week (not exactly unusual if we're being honest) while I was talking with a friend about the pros and cons of public vs. private LLMs. We work in wildly different industries, with vastly different AI experience — he's just starting to explore LLMs, and I've been building GPT-powered pipelines since the GPT-2 days — yet our perspectives on the tech, the people, and the problems lined up almost perfectly. Somewhere between bites (Just Eat It!), the line from Another One Rides The Bus popped into my head: "Ridin' in the bus down the boulevard, and the place was pretty packed… It was smellin' like a locker room // There was junk all over the floor…" It fit our conversation perfectly.

Cross-Site Request Forgery (CSRF, pronounced "sea-surf") is a sneaky and dangerous web vulnerability. Classified as CWE-352 by MITRE, it allows attackers to trick authenticated users into unknowingly submitting malicious requests to a web application. Imagine being logged into your bank account and clicking a seemingly harmless link that secretly instructs your browser to transfer funds to an attacker – that's CSRF in action. Why CSRF is Dangerous (CWE-352): Exploits Trust: The target site trusts the user's browser because it sends valid session cookies automatically with every request. User Unawareness: The victim executes the malicious action entirely unknowingly, often with a single click. Impact: Can lead to account takeover (changing email/password), unauthorized fund transfers,…  ( 7 min )

Introduction As software projects grow, so do their repositories. Large binary files, extensive histories, and sprawling codebases can turn simple Git operations into time-consuming ordeals. Cloning a repository shouldn't feel like downloading the entire internet, and checking out a branch shouldn't require a coffee break. Git Large File Storage (LFS) and sparse-checkout are two powerful features designed to solve these exact problems. Git LFS efficiently manages large binary files by storing them outside your repository, while sparse-checkout allows you to work with only the parts of a repository you need. Together, they transform unwieldy repositories into manageable, efficient development environments. This guide will show you how to implement both solutions, optimize your workflow fo…  ( 13 min )

Just as I was about to start using kiro in earnest, I came across a post on X by SimSta2 hinting at a possible change to the pricing plan. Full arthicle is here... Official announcement: Pricing plans are live Who’s affected by the new pricing plan Requires Kiro v0.2.13 or higher. Check from the profile menu in the top-right corner of the editor. When logging in with an IAM Identity Center ID that has Q Developer Pro, the Kiro Plan allowance display disappears, meaning you’re (probably) excluded from the new plan’s restrictions. Switching accounts doesn’t end your IDE-side Kiro sessions — they remain intact. Once you use up your free allowance, you’ll automatically switch to pay-per-use billing. Heavy users should be especially careful.  ( 5 min )
